MAX1692

General Description

Features

♦ 1.2A High-Efficiency 2.2MHz DC-DC Converter

The MAX16922 power-management integrated circuit

(PMIC) is designed for medium power-level automotive

applications and integrates multiple supplies in a small

footprint. The device includes one high-voltage step-

down converter (OUT1) and three low-voltage cascad-

ed DC-DC converters (OUT2, OUT3, OUT4). OUT1 and

OUT2 are step-down DC-DC converters, and OUT3/

OUT4 are linear regulators. The device also includes a

reset output (RESET) and a high-voltage-compatible

enable input (EN).

3.7V to 28V Operating Supply Voltage

45V Load-Dump Protection

Output Voltage: 3.0V to 5.5V

♦ 600mA High-Efficiency 2.2MHz DC-DC Converter

2.7V to 5.5V Supply Voltage

Output Voltage: 1.0V to 3.9V

180° Out-of-Phase Operation

Forced-PWM and Auto-PWM Modes

♦ LDO Linear Regulators

OUT3: 1.0V to 4.15V at 300mA

OUT4: 1.0V to 4.15V at 300mA

Separate Inputs for Increased Efficiency

The 1.2A output high-efficiency, step-down DC-DC con-

verter (OUT1) operates from a voltage up to 28V contin-

uous and is protected from load-dump transients up to

45V. The 600mA output high-efficiency step-down DC-

DC converter (OUT2) runs from a voltage up to 5.5V.

The two 300mA LDO linear regulators offer low dropout

of only 130mV (typ). The power-good RESET output

provides voltage monitoring for OUT1 and OUT2.

♦ Enable Input

♦ RESET Output Monitoring on OUT1 and OUT2

♦ Overtemperature and Short-Circuit Protection

♦ Available in

5mm x 5mm x 0.8mm, 20-Pin TQFN-EP

4.5mm x 6.5mm, 20-Pin TSSOP-EP

OUT1 and OUT2 use fast 2.2MHz PWM switching and

small external components. The high-voltage converter

(OUT1) enters skip mode automatically under light

loads to prevent an overvoltage condition from occur-

ring at the output. The low-voltage synchronous DC-DC

converter (OUT2) can operate in forced-PWM mode to

prevent any AM band interference or high-efficiency

auto-PWM mode.
