3V bus • High Performance DSPs, FPGAs, ASICs and Microprocessors • Broadband, Networking and Optical Communications Infrastructure DESCRIPTION The LM20133 is a full featured synchronous buck regulator capable of delivering up to 3A of continuous output current.
The current mode control loop can be compensated to be stable with virtually any type of output capacitor.
For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use.
The device is optimized to work over the input voltage range of 2.
95V to 5.
5V making it suited for a wide variety of low voltage systems.
The device features internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability.
A precision enable pin and integrated UVLO allows the turn on of the device to be tightly controlled and sequenced.
Start-up inrush currents are limited by both an internally fixed and externally adjustable Soft-Start circuit.
Fault detection and supply sequencing is possible with the integrated power good circuit.
The switching frequency of the LM20133 can be synchronized to an external clock by use of the SYNC pin.
