TEXAS INSTRUMENTS LM20143MHE/NOPB 直流-直流开关降压逐步递减稳压器, 可调, 2.95V-5.5V输入, 800mV-5V输出, 3A输出, HTSSOP-16
The is a full-featured PowerWise™ adjustable frequency 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 2.95 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 circuit 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.
