MAX16939ATESB/V+ Description
The MAX16939ATESB/V+ is a 3.5A current-mode step-down converter with integrated high-side and low-side MOSFETs designed to operate with an external Schottky diode for better efficiency. The low-side MOSFET enables fixed-frequency forced-PWM (FPWM) operation under light-load applications. The MAX16939ATESB/V+ works with input voltages from 3.5V to 36V, using only 28FA quiescent current at no load. The switching frequency is resistor programmable from 220kHz to 2.2MHz and can be synchronized to an external clock. The MAX16939ATESB/V+’s output voltage is available as 3.3V/5V fixed or adjustable from 1V to 10V. The wide input voltage range and its ability to operate at 98% duty cycle during Undervoltage transients make the MAX16939ATESB/V+ ideal for automotive and industrial applications.
