AAT2610

PRODUCT DATASHEET AAT2610 7-Channel PMU for Digital Still Cameras General Description The AAT2610 is a highly integrated power management solution specifically suited for Digital Still Camera (DSC) systems, featuring seven DC-DC switching regulators for maximum operating efficiency. The input operating voltage range is 1.6 to 5.5V, making the device an ideal solution for 1-cell Li-ion batteries, 2-cell alkaline batteries, and USB and regulated AC-DC wall adapters. All seven DC-DC switching regulators feature high efficiency light load operating mode to extend battery life while in low power standby state. Three different DC-DC building blocks provide maximum design flexibility: a boost (step-up) DC-DC controller with an output voltage range of 3.0V to 5.5V and a current mode control buck (step-down) or boost (step-up) DC-DC controller with an output voltage range of 2.5V to the step-up converter (SU) output voltage and buck output range of 0.6V to VIN. Dual current mode control synchronous buck regulators provide low voltage, low noise outputs required for system logic and memory. Output voltage range is 0.6V to VIN. The Auxiliary 1 boost (stepup) is ideally suited for LCD backlight and can drive 1-6 white LEDs with ±10% accuracy. PWM input controls LED dimming across the frequency range from 10% to 100% duty cycle. The integrated OVP and SCF feature protects the device from open-circuit LED conditions. The Auxiliary 2 boost (step-up) and Auxiliary 3 buckboost (inverting) ou...
