2.35V to 5.5V, 0.5% Accurate, 1MHz PWM

Step-Down Controllers with Voltage Margining

General Description

Features

The MAX1960/MAX1961/MAX1962 high-current, high-

efficiency voltage-mode step-down DC-DC controllers

operate from a 2.35V to 5.5V input and generate output

voltages down to 0.8V at up to 20A. An on-chip charge

pump generates a regulated 5V for MOSFET drive.

Additionally, adaptive dead-time drivers allow a

wide variety of MOSFETs to be used without risking

shoot-through.

o 0.5% Accurate Output

o Operates from 2.35V to 5.5V Supply

o Generates Low Output Voltage Down to 0.8V

o On-Chip Charge Pump Provides 5V Gate Drive

o Ceramic or Electrolytic Capacitors

o 94% Efficiency

o External Synchronization from 450kHz to 1.2MHz

o 500kHz/1MHz Fixed-Frequency PWM Operation

o Fast Transient Response

Fixed-frequency PWM operation and external synchro-

nization make these controllers suitable for telecom

and datacom applications. The operating frequency is

programmable to either 500kHz or 1MHz, or from

450kHz to 1.2MHz with an external clock. A clock output

is provided to synchronize another converter for 180°

out-of-phase operation. A high closed-loop bandwidth

provides excellent transient response for applications

with dynamic loads.

o Two Converters Can Operate 180° Out-of-Phase

4% Voltage Margining for System Test

o 10% Accurate Current Sensing (MAX1962)

o Adaptive Dead Time Prevents Shoot-Through

Lossless current sensing in the MAX1960 and

MAX1961 is achieved by monitoring the drain-to-source

voltage of the low-side external FET. The current limit is

scalable to accommodate a wide variety of MOSFETs

and load currents. The MAX1962 has 10% accurate

sense-resistor-based current limiting.

The MAX1960 and MAX1962 have an adjustable output

voltage from 0.8V to 4.95V. The MAX1961 and

MAX1962 have four preset output voltages (1.5V, 1.8V,

2.5V, and 3.3V) and feature 0.5% voltage accuracy

over temperature, line, and load variations. The

MAX1960 and MAX1961 also feature voltage-margining

control inputs that shift the output voltage up or down

by 4% for system testing.
