RT5035A / RT5035B 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.
