AnalogicTech Reports Financial Results for the Second Quarter 2010 Jul 28, 2010 - Net revenue for the second quarter of 2010 was $23.1 million, an increase of 0.7% over net revenue of $23.0 million for the second quarter of 2009 and a sequential increase of 6% from net revenue of $21.9 million for the first quarter of 2010. In accordance with U.S. generally accepted accounting principles (GAAP), net loss for the second quarter of 2010 was $3.9 million, or $0.09 per diluted share. This compares to GAAP net loss of $2.5 million, or $0.06 per diluted share for the second quarter of 2009, and GAAP net loss of $4.2 million, or $0.10 per diluted share, for the first quarter of 2010. On a non-GAAP basis, net loss for the second quarter of 2010 was $2.7 million, or $0.06 per diluted share. This compares to non-GAAP net loss of $0.8 million, or $0.02 per diluted share, for the second quarter of 2009 and non-GAAP net loss of $2.9 million, or $0.07 per diluted share, for the first quarter of 2010. |

AAT1405: 4 Channel LED Backlight Driver with Integrated Boost and High Frequency Direct PWM Dimming Jun 28, 2010 |
|
AAT1401: Serial LED Driver with Filtered PWM and 32 Step S²C Dimming Control Jun 1, 2010 - The AAT1401, AAT1402, AAT1403 and AAT1410 are step-up single channel LED driver with an input voltage range of 2.7V to 5.5V. Parts of the AAT14xx family can drive up to 10 LEDs in a single string. The wide input voltage range, small solution size, advanced dimming features and high efficiency is suitable for LED backlight solutions for single cell Li-ion based equipment. A precision, high voltage current sink maintains the maximum LED current that can be set from 10 to 31mA by a single external resistor. The high switching frequency supports ultra small, low-cost filter components. Two dimming controls are available; 32 dimming steps using the S²Cwire™ interface, and filtered or direct PWM control (dependent on part number). The frequency range of the PWM dimming extends up to 100 kHz and eliminates audible noise and is suitable for CABC (Content Adaptive Brightness Control) applications. The device includes over-temperature protection, programmable over-voltage protection and automatic recovery when the faults are removed. The AAT140x family is available in a 10-pin wafer-level chip scale package (WLCSP) and is rated over the -40°C to +85°C temperature range. |

AAT2869: Fade-In/Fade-Out 4 Channel Backlight Driver with Dual LDOs May 28, 2010 - The AAT2869 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.5x) conversion to maximize efficiency for white LED applications. The AAT2869 is capable of driving 4 white LEDs at a total of 124mA from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher-current LEDs. A low external parts count (two 1μF flying capacitors and two small 1μF capacitors at IN and OUTCP) makes the AAT2869 ideally suited for small battery-powered applications. The fade-in/fade-out feature makes backlight turn-on/turn-off more visual comfortable. The AAT2869 also includes two 150mA low, drop-out linear regulators as additional power supplies for display and related camera power. The LDO voltage is also programmable. AnalogicTech’s Advanced Simple Serial Control™ (AS2Cwire™) serial digital input is used to enable, disable and set the maximum LED current to one of 32 levels for the LEDs, to enable/disable the LDOs, and to set the LDO's output. The programmable LED current ranges from 31mA to 0.4mA. Each output of the AAT2869 is equipped with built-in protection for short-circuit and auto-disable for load short-circuit conditions. The soft-start circuitry prevents excessive inrush current at charge pump start-up and mode transitions. The AAT2869 is available in the Pb-free, space-saving TQFN3.0x2.2-18L package, and operates over the -40°C to 85°C ambient temperature range. |

AAT2868: CABC Compatible 4 Channel Backlight Driver with Dual LDO Regulators May 28, 2010 - The AAT2868 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.5x) conversion to maximize efficiency for white LED Content Adaptive Brightness Control (CABC) applications. The AAT2868 is capable of driving 4 white LEDs at a total 124mA from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher-current LEDs. A low external parts count (two 1μF flying capacitors and two small 1μF capacitors at IN and OUTCP) makes the AAT2868 ideally suited for small battery-powered applications. The AAT2868 also includes two 150mA low dropout (LDO) linear regulators as additional power supplies for display and related camera power. The LDO voltage is also programmable. AnalogicTech’s Advanced Simple Serial Control™ (AS2Cwire™) serial digital input is used to enable, disable and set the maximum LED current to one of 32 levels for the LEDs. The current ranges from 31mA to 0.4mA. An external PWM input is adopted to dim the LED current from 100% to 1% of the maximum LED current by varying the PWM duty cycle with frequencies up to 100kHz. To eliminate flicker or noise associated with PWM control, the input PWM signal is filtered to provide a steady state output current. Each output of the AAT2868 is equipped with built-in protection for short-circuit and auto-disable for load short-circuit conditions. The soft-start circuitry prevents excessive inrush current at charge pump start-up and mode transitions. The AAT2868 is available in the Pb-free, space-saving TQFN3.0x2.2-18L package, and operates over the -40°C to 85°C ambient temperature range. |
