RK809 Datasheet Rev 2.3 Rockchip RK809 Datasheet Revision 2.3 March.2023 Copyright ©2023 Rockchip Electronics Co., Ltd. 1 RK809 Datasheet Rev 2.3 Chapter 1 Introduction 1.1 Overview The device also contains 9 LDO regulators, two switches and a battery fuel gauge. Powerup/power-down controller is configurable and can support any customized powerup/power-down sequences (OTP based). A real-time clock (RTC) is also integrated to provide a 32.768-kHz output buffer, and real time function. The RK809 supports 32.768kHz clock generation based on a crystal oscillator. It also includes Audio CODEC , real ground Head phone driver and ClassD driver. The RK809 integrates four channels step-down DC-DC converters. All of them adopt ripple base control to achieve very fast load transient response. Meanwhile, all of them can dynamically adjust the output voltage, as required by the processor based on the processor’s operation status so as to maximize the system efficiency. The output voltages of most channels can be configured through the I2C interface.
