MAX16935/MAX16939 EVALUATION KIT AVAILA BLE 36V, 3.5A, 2.2MHz Step-Down Convert ers with 28µA Quiescent Current Gener al Description The MAX16935/MAX16939 ar e 3.5A current-mode stepdown converters with integrated high-side and lowside MOSFETs designed to operate with an ext ernal Schottky diode for better efficie ncy. The low-side MOSFET enables fixed- frequency forced-PWM (FPWM) operation u nder light-load applications. The devic es operate with input voltages from 3.5 V to 36V, while using only 28FA quiesce nt current at no load. The switching fr equency is resistor programmable from 2 20kHz 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 al ong with its ability to operate at 98% duty cycle during undervoltage transien ts make the devices ideal for automotiv e and industrial applications. Under li ght-load applications, the FSYNC logic input allows the devices to either o
