MAX16930 - (MAX16930 / MAX16931) Dual Buck

General Description

The MAX16930/MAX16931 offer two high-voltage, synchronous step-down controllers and a step-up preboost controller.

They operate with an input voltage supply from 2V to 42V with preboost active and can operate in drop-out condition by running at 95% duty cycle.

Key Features

  • include cycle-by-cycle current limit and thermal shutdown. The devices are available in a 40-pin TQFN-EP package and are specified for operation over the -40NC to +125NC automotive temperature range. S Dual, 2MHz Step-Down Controllers S Preboost for Operation to 2V S 180° Out-of-Phase Operation S 50ns Minimum On-Time Allows 3.3V Output from Car Battery at 2.2MHz S 20µA Operating Current S Wide Input Supply Range from 3.5V to 36V (without Preboost) S Resistor Programmable Frequency Between.

EVALUATION KIT AVAILABLE MAX16930/MAX16931 2MHz, 36V, Dual Buck with Preboost and 20µA Quiescent Current General Description The MAX16930/MAX16931 offer two high-voltage, synchronous step-down controllers and a step-up preboost controller. They operate with an input voltage supply from 2V to 42V with preboost active and can operate in drop-out condition by running at 95% duty cycle. The devices are intended for applications with mid- to high-power requirements that operate at a wide input voltage range such as during automotive cold-crank or engine stop-start conditions. The MAX16930/MAX16931 step-down controllers operate 180N out-of-phase at frequencies up to 2.2MHz to allow small external components, reduced output ripple, and to guarantee no AM band interference.
