MAX16935RATE/V+

The MAX16935RATE/V+ is a 36V, 3.5A, 2.2MHz step-down converter with 28µA quiescent current in 16 pin TQFN-EP package. The 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 device operates with input voltages from 3.5V to 36V while using only 28µA 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 device output voltage is 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. It operates in skip mode, forced fixed-frequency operation and external frequency synchronization.
