Voltage Regulators - DC DC Switching Regulators datasheet and documents for MAX16939ATESA/V+

MAX16939ATESA/V+

Voltage Regulators - DC DC Switching Regulators Overview

The MAX16939ATESA/V+ is a 3.5A current-mode step-down converter with integrated high-side and low-side MOSFETs, designed for operation with an external Schottky diode. It operates from a 3.5V to 36V input range with 28µA quiescent current. The switching frequency is resistor-programmable from 220kHz to 2.2MHz or synchronized externally. Output voltage is adjustable from 1V to 10V or fixed at 3.3V/5V. It features cycle-by-cycle current limit, thermal shutdown, and power-good monitoring in a 16-pin TQFN-EP package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side and low-side MOSFETs enable efficient step-down conversion with external Schottky diode support.
Resistor-programmable switching frequency up to 2.2MHz allows optimization for size and efficiency.
Fixed-frequency forced-PWM mode minimizes EMI for RF transceiver applications.
Power-good monitor facilitates precise power-supply sequencing.
