Ricoh RP904Z Series PWM/PFM Step-Down DC/DC Converters Datasheet
The RP904 series are CMOS-based PWM/PFM step-down DC/DC converters featuring synchronous rectification, low supply current, and a through mode. The RP904Z model includes an oscillator, PWM/PFM control circuit, error amplifier, and various protection circuits such as UVLO and latch-type over-current protection. It supports output voltage selection via the VSEL pin and allows operation switching between PWM and PFM modes based on load current and user configuration.
