Nisshinbo RP510L 4A Forced PWM Step-down DC/DC Converter
Nisshinbo RP510L 4A Forced PWM Step-down DC/DC Converter with Synchronous Rectifier brings the simplicity of power sequencing with adjustable soft-start and power-good functions. The RP510L has a low input voltage of 2.5V to 5.5V and an output voltage range of 0.8V to 3.3V. Ideally, latch type and foldback type protection are user-selectable when released automatically from the overcurrent protection. The small package size DFN3030-12 provides the RP510L with a high-density mounting.
