Product Summary

The AAT1415A is an integrated 5-channel pulse-width-modulation (PWM) solution and a low noise LDO for the power supply of DC-DC converter. The AAT1415A improves performance and size compared to conventional controllers in battery design. It has three current mode PWM converters (CH1, CH2, and CH3) and two voltage mode PWM converters (CH4 and CH5). Each current-mode channel has on-chip synchronous power FETs. It is ideal for: (1)Digital Still Cameras; (2)Digital Videos; (3)PDAs; (4)Portable Devices.
