MAX16939

MAX16935/MAX16939 EVALUATION KIT AVAILABLE 36V, 3.5A, 2.2MHz Step-Down Converters with 28µA Quiescent Current General Description The MAX16935/MAX16939 are 3.5A current-mode stepdown converters with integrated high-side and lowside 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 devices operate with input voltages from 3.5V to 36V, while 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 devices’ output voltage is available as 3.3V/5V fixed or adjustable from 1V to 10V. The wide input voltage range along with its ability to operate at 98% duty cycle during undervoltage transients make the devices ideal for automotive and industrial applications. Under light-load applications, the FSYNC logic input allows the devices to either o...
