RICOH Electronic Devices Co., Ltd. RP514

Ultra-low Power Consumption 100 mA Buck DC/DC Converter with Battery Monitor


TopologyBuck Converter
Input voltage1.8-5.5 V
Switching frequency1000 kHz
Output 14 V / 0.1 A


The RP514x is a buck DC/DC converter with a Battery Monitor (BM) featuring ultra-low current and low-voltage resistance.The battery monitor divides the input voltage (VIN) into 1/3 or 1/4, and directly provides the MCU’s built-in low voltage AD converter with buffered voltage without external circuits.
