RT7299B

8A, 18V, Synchronous Step-Down Converter

General Description

Features

^Low R_DS(ON)Power MOSFET Switches 26mΩ/19mΩ

^Input Voltage Range : 4.5V to 18V

^Adjustable Switching Frequency : 200kHz to 1.6MHz

^Current-Mode Control

The RT7299B is a high efficiency, monolithic synchronous

step-downDC/DC converter that can deliver up to 8Aoutput

current from a 4.5V to 18V input supply. The RT7299B

current-mode architecture with external compensation

allows the transient response to be optimized over a wide

range of loads and output capacitors. Cycle-by-cycle

current limit provides protection against shorted outputs

and soft-start eliminates input current surge during start-

up. Fault condition protections include output under-voltage

protection, output over-voltage protection, and over-

temperature protection. The low current shutdown mode

provides output disconnection, enabling easy power

management in battery-powered systems.

^Synchronous to External Clock : 200kHz to 1.6MHz

^Accurate Voltage Reference 0.6V 1%

^Monotonic Start-Up into Pre-biased Outputs

^Adjustable Soft-Start

^Power Good Indicator

^Input Under-Voltage Lockout

^Selectable Hiccup Mode and Latch-Off Mode

Under-Voltage Protection

 Over-Temperature and Over-Voltage Protection

 RoHS Compliant and Halogen Free
