LM20136 is a full-featured synchronous buck regulator capable of delivering up to 6A of continuous output current. It can compensate for the current mode control loop and can be stable with almost any type of output capacitor. In most cases, the compensation device, which requires only two external elements, provides maximum flexibility and ease of use. The device is optimized to operate in a wide range of input voltages from 2.95V to 5.5V for low-voltage systems.

The device features internal overvoltage protection (OVP) and overcurrent protection (OCP) circuitry, enhancing system reliability. A high-precision enable pin and integrated undervoltage lockout allow for tight control and sequencing of the device. Both a fixed internal and external adjustable soft-start circuit with limited start-up inrush current. Possible with integrated power supply good circuit fault detection and power sequencing.

LM20136 switching frequency can be synchronized to an external clock using the SYNC pin. The SYNC pin synchronizes the input signal from 500 kHz to 1.5 MHz

LM20136 work in multi-rail power architecture design. The output voltage of the device can be configured to track a higher voltage rail using SS/TRK pins. If the LM20136's output prebias starts, it will not pull the output low.

LM20136 is available in a 16-pin eTSSOP package that can be soldered to the PCB with bare pads, eliminating the need for bulky heatsinks.
