概述

The RP515 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 to a buffer output and inputs a signal directly into the MCU’s built-in low voltage AD converter without external circuits. It is suitable for use in wearable and IoT devices that require miniaturization and long-lifetime of battery.

特点

Ultra-low consumption current (I_Q: 0.3 µA) with the VFM control for DC/DC (switching frequency: 1 MHz max.)
High efficiency under light load conditions
Reducing components and space by combining DC/DC and BM into a single chip
Suitable for coin batteries and USB ports due to its wide input voltage range from 1.8 V to 5.5 V
