The MAX16952AUE/V+ from Maxim Integrated Products is a 36V, 2.2MHz step down controller with low operating current in 16 pin TSSOP package. The MAX16952AUE/V+ 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 MAX16952AUE/V+ 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 MAX16952AUE/V+ 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.
