Chapter 1 Introduction
1.1 Overview
The RK806 is a complex power-management integrated circuit (PMIC). The RK806 can
provide a complete power management solution with very few external components.
The RK806 provides 10 fast load transient synchronous step-down converters. The device
also contains 6 LDO regulators, 5 NMOS LDO regulators for high efficiency. Power-up/powerdown controller is configurable and can support any customized power-up/power-down
sequences (OTP based).
The RK806 integrates 10 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 or SPI interface. The inputs of all channels have
soft start function, which greatly reduces the inrush current at the startup. 2MHz switching
frequency and good control method decrease the external inductance and capacitance.
The RK806 integrates 6 channels LDO regulators. The inputs of all LDO regulators
could be decrease to 2V for high convert efficiency. Meanwhile 5 channels NMOS LDO
regulators are integrated. The output voltages of all LDO regulators can be configured through
the I2C or SPI interface.
Two RK806 could work together that one of them is master, another is slave. The powerup/power-down sequences could be synchronization.
The RK806 is available in a QFN68 7.0 mm x 7.0 mm package, with a 0.35-mm pin pitch.

1. Coplanarity applies to leads, corner leads and die attach pad.
2. Dimension b applies to metalized terminal and is measured between 0.15mm and 0.30mm from the
terminal tip. If the terminal has the optional radius on the other end of the terminal, the dimension
b should not be measure in that radius area.
