MAX20022 - Step-Down DC-DC Converters

Download the MAX20022 datasheet PDF. This datasheet also covers the MAX20021 variant, as both devices belong to the same step-down dc-dc converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX20021/MAX20022 power-management ICs (PMICs) integrate four low-voltage, high-efficiency, stepdown DC-DC converters.

Each of the four outputs is factory or resistor programmable between 1.0V to 4.0V and can deliver up to 1.0A of current.

Key Features

  • including: input overvoltage protection, input undervoltage monitoring, input undervoltage lockout, cycle-by-cycle current limiting, and overtemperature shutdown. The input undervoltage monitor indicates a brownout condition by driving PG_ low when the input falls below the UVM threshold. The MAX20021/MAX20022 PMICs are available in a 28-pin TQFN package with an exposed pad and are specified for operation over the -40ºC to +125ºC automotive temperature range.

MAX20021/MAX20022 EVALUATION KIT AVAILABLE Automotive Quad, Low-Voltage Step-Down DC-DC Converters General Description The MAX20021/MAX20022 power-management ICs (PMICs) integrate four low-voltage, high-efficiency, stepdown DC-DC converters. Each of the four outputs 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 pointof-load and post-regulation applications. The PMICs feature fixed-frequency PWM-mode operation with a switching frequency of 2.2MHz or 3.2MHz. Highfrequency operation allows for an all-ceramic capacitor design and small-size external components.
