The LM20136 is a full-featured synchronous buck regulator that provides up to 6A of continuous output current capability. The current mode controls loop compensation and can be stabilized with almost any type of output capacitor. In most cases, the compensation device requires only two external components, providing maximum flexibility and ease of use. The device is suitable for operation over a wide range of input voltages from 2.95V to 5.5V, making it a suitable temperature range for a low-voltage system.
The device has internal overvoltage protection (OVP) and overcurrent protection circuitry to improve system reliability (OCP). Precise enable pins and integrated undervoltage lockout allow for tightly controlled and sequencing devices to power the device. Start-up inrush current limit, both internally fixed and externally adjustable soft-start circuitry. Fault detection and power sequencing are good circuits that may be integrated with the power supply.
The switching frequency of this LM20136 can be synchronized to the sync pin of an external clock. The SYNC pin is a synchronized input signal range from 500 kHz to 1.5 MHz
The LM20136 is designed to work on a multi-rail power supply with a well-structured structure. The output voltage of the device can be set to a higher voltage rail tracking using stainless steel/Tielck pins. If the LM20136 output is pre-biased when started, it will not pull the output low.
The LM20136 is available in a 16-pin eTSSOP package with bare pads that can be soldered to printed circuit boards, eliminating the need for bulky heatsinks.
