RAA270005KFP集成電路（IC）的電源管理-專用規(guī)格書PDF中文資料

Description

The RAA270005KFP is a general-purpose Power Management IC (PMIC), and suitable for RENESAS

RH850/P1x series microcontroller (MCU). The features and the details of the PMIC are described in this

document.

The PMIC contains two types of DCDCs converters: buck and boost, two low dropout linear regulators

(LDO) and two linear trackers.

The switching frequency of boost/buck DCDCs are typical 420 kHz, 2.1 MHz respectively.

Monitor functions for the internal status are implemented. Input voltage, output of all regulators, and

internal analog voltage corresponding to temperature can be monitored through ADC of MCU. And

reference voltage can be monitored for testing the ADC of MCU as well.

The PMIC has sequencer circuits for controlling power-up/down, therefore any external sequencer

circuits are unnecessary. And the PMIC can control an external backup-power for MCU.
