RT8800/B

General Purpose 2/3-Phase PWM Controller for High-Density

Power Supply

General Description

Features

^ꢀ5V Power Supply Voltage

The RT8800/B are general purpose multi-phase

synchronous buck controllers dedicating for high density

power supply regulation. The parts implement 2, and 3

buck switching stages operating in interleaved phase set

automatically. The output voltage is regulated and

controlled following the input voltage of FB pin. With such

a single analog control, the RT8800/B provide a simple,

flexible, wide-range and extreme cost-effective high-

density voltage regulation solutions for various high-density

power supply application. The RT8800/B multi-phase

architecture provide high output current while maintaining

low power dissipation on power devices and low stress

on input and output capacitors. The high equivalent

operating frequency also reduces the component

dimension and the output voltage ripple in load transient.

^ꢀ2/3-Phase Power Conversion with Automatic Phase

Selection (RT8800 : 2/3-Phase, RT8800B : 2-Phase)

^ꢀOutput Voltage Controlled by External Reference

Voltage

^ꢀPrecise Core Voltage Regulation

^ꢀPower Stage Thermal Balance by DCR Current

Sensing

^ꢀExtreme Low-Cost, Lossless Time Sharing Current

Sensing

^ꢀInternal Soft-start

^ꢀHiccup Mode Over-Current Protection

ꢀ Over-Voltage Protection

ꢀ Adjustable Operating Frequency and Typical at

300kHz Per Phase

RT8800/B implement both voltage and current loops to

achieve good regulation, response and power stage

thermal balance. The RT8800/B apply the time sharing

DCR current sensing technology newly as well; with such

a topology, the RT8800/B extract the DCR of output

inductor as sense component to deliver a more precise

load line regulation and better thermal balance capability.

Moreover, the parts monitor the output voltage for over-

current and over-voltage protection; Soft-start and

programmable under-voltage lockout are also provided to

assure the safety of power system.
