Product Details
The MAX16952 is a current-mode, synchronous PWM step-down controller designed to operate with input voltages from 3.5V to 36V while using only 50µA of quiescent current at no load. The switching frequency is adjustable from 1MHz to 2.2MHz by an external resistor and can be synchronized to an external clock up to 2.4MHz. The MAX16952 output voltage is pin programmable to be either 5V fixed or adjustable from 1V to 10V. The wide input voltage range, along with its ability to operate in dropout during undervoltage transients, makes it ideal for automotive and industrial applications.
The MAX16952 operates in fixed-frequency PWM mode and low quiescent current skip mode. It features an enable logic input, which is compatible up to 42V to disable the device and reduce its shutdown current to 10µA. Protection features include overcurrent limit, overvoltage, undervoltage, and thermal shutdown with automatic recovery. The device also features a power-good monitor to ease power-supply sequencing.
The MAX16952 is available in a thermally enhanced 16-pin TSSOP package with exposed pad, and is specified for operation over the -40°C to +125°C automotive temperature range.
