Renesas Electronics RAA210030 Step-Down DC/DC Mini Power Module is a compact, single-channel, synchronous step-down, non-isolated complete power supply delivering up to 3A of continuous current. This power supply module operates from a single 2.7V to 5.5V input power rail and integrates the controller, gate driver, power inductor, and MOSFETs. The RAA210030 power supply employs a peak current mode control scheme to provide a fast transient response and excellent loop stability. The output voltage can be set as low as 0.6V, with setpoint accuracy better than ±1.5% over line, load, and temperature.
The RAA210030 power module can be configured for Pulsed Frequency Modulation (PFM) or Forced Pulse Width Modulation (FPWM) at light load. The FPWM reduces noise and RF interference, while PFM provides higher efficiency by reducing switching losses at light loads. Typical applications include telecom, industrial, optical, and medical equipment, point-of-load conversions, MCUs, MPUs, DSPs, and FPGAs.
