MAX16907

36V, 2.2MHz Step-Down Converter

with Low Operating Current

General Description

Features

The MAX16907 is a 3A, current-mode, step-down con-

verter with an integrated high-side switch. The device is

designed to operate with input voltages from 3.5V to 36V

while using only 30FA quiescent current at no load. The

switching frequency is adjustable from 1MHz to 2.2MHz

by an external resistor and can be synchronized to an

external clock. The output voltage is pin selectable to

be 5V fixed or adjustable from 1V to 10V. The wide input

voltage range along with its ability to operate at high duty

cycle during undervoltage transients make the device

ideal for automotive and industrial applications.

S Wide 3.5V to 36V Input Voltage Range

S 42V Input Transients Tolerance

S High Duty Cycle During Undervoltage Transients

S 5V Fixed or 1V to 10V Adjustable Output Voltage

S Integrated 3A Internal High-Side (70mI typ)

Switch

S Fast Load-Transient Response and Current-Mode

Architecture

S Adjustable Switching Frequency (1MHz to 2.2MHz)

S Frequency Synchronization Input

S 30µA Standby Mode Operating Current

S 5µA Typical Shutdown Current

The device operates in skip mode for reduced current

consumption in light-load applications. Protection fea-

tures include overcurrent limit, overvoltage, and thermal

shutdown with automatic recovery. The device also

features a power-good monitor to ease power-supply

sequencing.

S Spread Spectrum (Optional)

S Overvoltage, Undervoltage, Overtemperature, and

Short-Circuit Protections

The device operates over the -40NC to +125NC automo-

tive temperature range, and is available in 16-pin TSSOP

and TQFN (5mm x 5mm) packages with exposed pads.
