Introduction

AI Translation

LM5175 is a synchronous 4-switch buck-boost DC/DC controller that regulates the output voltage at, above, or below the input voltage. With a wide input voltage range of 3.5V to 42V (60V maximum), the LM5175 supports a broad range of applications. The LM5175 employs current-mode control in both buck and boost operating modes to deliver excellent load and line regulation performance. 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 various protection functions including cycle-by-cycle current limiting, input undervoltage lockout (UVLO), output overvoltage protection (OVP), and thermal shutdown. In addition, the LM5175 offers selectable CCM or DCM operation, selectable average input or output current limiting, optional spread spectrum to reduce peak EMI, and optional hiccup-mode protection for sustained overload conditions.
