MAX20031 - Front-End Power Supply

Download the MAX20031 datasheet PDF. This datasheet also covers the MAX20030 variant, as both devices belong to the same front-end power supply family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX20030/MAX20031 ICs are automotive 2.2MHz dual-synchronous step-down controllers with preboost controller and low-IQ LDO.

The preboost controller enables VOUT1 and VOUT2 to stay in regulation during coldcrank operation all the way down to a battery input of 2V.

Key Features

  • include cycleby-cycle current limit and thermal shutdown. The MAX20030/MAX20031 are specified for operation over the -40°C to +125°C automotive temperature range.

Dual Buck, Sync Boost, and LDO—Complete Front-End Power Supply with 17μA IQ General Description The MAX20030/MAX20031 ICs are automotive 2.2MHz dual-synchronous step-down controllers with preboost controller and low-IQ LDO. The preboost controller enables VOUT1 and VOUT2 to stay in regulation during coldcrank operation all the way down to a battery input of 2V. The ICs offer two high-voltage synchronous step-down controllers that operate 180 degrees out of phase. This device operates with an input-voltage supply from 3.5V to 42V and can operate in dropout conditions by running at 97% duty cycle.
