RT5035A/B is a highly-integrated DSC Power Management IC that contains 7ch switching DC/DC converters and two generic LDOs, one keep-alive low-quiescent LDO for RTC, one load switch with soft-start control and current limit, a switch with reverse leakage prevention for backup battery, and a Real-Time-Clock (RTC) including time counter and 32768Hz oscillator. The DC/DC converters are one low-voltage Step-Up operated in either Async-PFM or Sync-PWM, one current mode Sync Step-Up/Down (Buck-Boost), four Sync Step-Down, and one Asyn Step-Up for WLED driver. All power MOS are integrated. And compensation networks are built in. RT5035A/B uses I2C interface to set power-on and power-off timing, output voltage, and WLED current and dimming level, and also access RTC time counters and oscillator fine-tuning. RT5035A/B dedicate for CMOS image sensor application by providing one Sync Step-Down, one LDO, and one load switch. The RT5035A/B also provides rich protection functions include Over-Current Protection, Under-Voltage Protection, Over-Voltage Protection, Over- Temperature Protection, and Over-Load Protection. RT5035A/B is available in WQFN-40L 5x5 package.
