illustrate

The LM20333 is a full-featured synchronous buck regulator capable of delivering up to 3A of load current. External current-mode control loop compensation, consisting of only two parts, provides both high performance and ease of use. The device is optimized for operation from a 4.5V to 36V input voltage range, making it suitable for high voltage systems.

The device features internal overvoltage protection (OVP) and overcurrent protection (OCP) circuitry to improve 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 externally adjustable soft-start circuit limits the inrush current at startup. Possible with integrated power good (PGOOD) circuit fault detection and power sequencing.

The LM20333 is designed to work on a multirail power architecture. The output voltage of the device can be configured to track a higher voltage rail, using SS/TRK pins. If the output of the LM20333 is prebiased when it is turned on, it does not sink current and pull the output low until the internal soft-start ramp exceeds the voltage feedback pin.

The switching frequency of the LM20333 can be synchronized to an external clock using the SYNC pin. The SYNC pin synchronizes the input signal range from 250 kHz to 1.5 MHz.

The LM20333 is a 20-pin eTSSOP package with an exposed pad that can be soldered to a PCB, eliminating the need for bulky heat sinks.
