The LM20154MH/NOPB is a full-featured synchronous Buck Regulator capable of delivering up to 4A 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 2.95 to 5.5V making it suited for a wide variety of low voltage systems. The device features internal overvoltage protection (OVP) and overcurrent 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. Startup 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.
