Product Overview
The LM5175PWPT is a synchronous four-switch Buck-Boost DC/DC Controller, capable of regulating the output voltage at, above or below input voltage. It operates over a wide input voltage range of 3.5 to 42V (60V maximum) to support a variety of applications. It employs current-mode control both in buck and boost modes of operation for superior load and line regulation. The switching frequency is programmed by an external resistor and can be synchronized to an external clock signal. The device also features a programmable soft-start function and offers protection features including cycle-by-cycle current limiting, input under-voltage lockout (UVLO), output overvoltage protection (OVP) and thermal shutdown. In addition, it features selectable Continuous Conduction Mode (CCM) or Discontinuous Conduction Mode (DCM) operation, optional average input or output current limiting, optional spread spectrum to reduce peak EMI and optional hiccup mode protection in sustained overload conditions.
