SLUS970 –MARCH 2011

4.5-V TO 60-V WIDE-INPUT SYNCHRONOUS PWM BUCK CONTROLLER

Check for Samples: TPS40170

FEATURES

DESCRIPTION

TPS40170 is a full-featured, synchronous PWM buck

controller that operates at an input voltage between

•

Wide-Input Voltage Range from 4.5 V to 60 V

600-mV Reference Voltage with 1% Accuracy

Programmable UVLO and Hysteresis

4.5

V and 60 V and is optimized for high-

power-density, high-reliability DC/DC converter

applications. The controller implements voltage-mode

control with input-voltage feed-forward compensation

that enables instant response to input voltage

change. The switching frequency is programmable

from 100 kHz to 600 kHz.

Voltage Mode Control With Voltage Feed

Forward

•

Programmable Frequency Between 100 kHz

and 600 kHz

Bi-directional -Frequency Synchronization

With Master/Slave Option

The TPS40170 has a complete set of system

protection and monitoring features such as

programmable UVLO, programmable overcurrent

protection (OCP) by sensing the low-side FET,

selectable short-circuit protection (SCP) by sensing

the high-side FET and thermal shutdown. The

ENABLE pin allows for system shutdown in a

low-current (1-µA typical) mode. The controller

supports pre-biased output, provides an open-drain

PGOOD signal, and has closed loop soft-start, output

voltage tracking and adaptive dead-time control.

Low-side FET Sensing Overcurrent Protection

and High-Side FET Sensing Short-Circuit

Protection With Integrated Thermal

Compensation

•

Programmable Closed Loop Soft-Start

Supports Pre-Biased Outputs

Thermal Shutdown at 165°C with Hysteresis

Voltage Tracking

TPS40170 provides accurate output voltage

regulation via 1% ensured accuracy. Additionally, the

controller implements a novel scheme of bi-directional

synchronization with one controller acting as the

master and other downstream controllers acting as

slaves synchronized to the master in-phase or 180°

out-of-phase. Slave controllers can be synchronized

to an external clock within ±30% of the free running

switching frequency.
