® RT8553A Dual-Output Synchronous DC/DC Converter General Description The RT8553A is a dual-output DC/DC converter which is designed to provide the power for consumer products. It integrates a Boost converter and an inverting-Boost converter for enhancing the overall system efficiency of battery powered products. The RT8553A operates in Forced CCM mode for light load and heavy load condition. The high frequency allows for reduction of external components. In shutdown mode, the RT8553A consumes less than 1μA current. The RT8553A provides soft-start, OCP, OTP, OVP and UVLO function. The RT8553A is available in the tiny UDFN-12L 3x3 package to achieve best solution for saving PCB space and total BOM cost saving considerations.
