Introduction

AI Translation

LM5176 is a synchronous 4-switch buck/boost DC/DC controller capable of regulating the output voltage at a level equal to, higher than, or lower than the input voltage. The LM5176 operates over a wide input voltage range of 4.2V to 55V (60V absolute maximum), supporting a wide variety of applications. The LM5176 employs current control mode in both buck and boost operating modes to deliver excellent load and line regulation performance. The switching frequency is programmable via an external resistor and can be synchronized to an external clock signal. The device also features programmable soft-start and provides a comprehensive set of protection features including cycle-by-cycle current limiting, input undervoltage lockout (UVLO), output overvoltage protection (OVP), and thermal shutdown. Optional average input or output current limiting, optional spread spectrum for reduced peak EMI, and optional hiccup mode protection under sustained overload conditions are also available.
