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.

Product Detail

The MAX16952 evaluation kit (EV kit) is a fully assembled and tested PCB that contains all the components necessary to evaluate the performance of the MAX16952 synchronous PWM step-down controller. The device is available in a 16-pin TSSOP package and features an exposed pad for enhanced thermal dissipation.
The EV kit requires a 6V to 36V power supply for normal operation. The EV kit output is configured to 5V and can deliver up to 5A output current. The EV kit can be easily reconfigured to operate the controller in continuous PWM mode, SKIP mode, or external synchronization operation. The controller switching frequency is set to 2.2MHz. The EV kit includes a jumper to enable the circuit and an LED to monitor the power-good output.
