Part Overview
Description
The MAX20021/MAX20022 power-management ICs (PMICs) integrate four low-voltage, high-efficiency, step-down DC-DC converters. Each output is factory or resistor programmable between 1.0V to 4.0V and can deliver up to 1.0A of current. The PMICs operate from 3.0V to 5.5V, making them ideal for automotive point-of-load and post-regulation applications.

Features
Quad step-down DC-DC converters with integrated FETs
Operate from 3.0V to 5.5V supply voltage
1.0V to 4.0V fixed or adjustable output voltage
2.2MHz (MAX20022) or 3.2MHz (MAX20021) switching frequency
Four channels capable of delivering up to 1A each
Designed to improve automotive EMI performance
Forced-PWM operation
Two channels 180° out-of-phase. SYNC input
Spread-spectrum option
Soft-start and supply sequencing reduces inrush current
Individual enable inputs and power-good outputs to simplify sequencing
OV/UV input-voltage monitoring
Overtemperature and short-circuit protection
28-pin (5mm x 5mm x 0.8mm) TQFN-EP package
-40°C to 125°C operating temperature range
