【Shenzhen Mingjiada Electronics Co., Ltd.】Supply LM5176QPWPRQ1——[TI] 55V Wide VIN Synchronous 4-Switch Buck-Boost Controller

LM5176QPWPRQ1 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage.

LM5176QPWPRQ1 operates over a wide input voltage range of 4.2 V to 55 V (60 V absolute maximum) to support a variety of applications.

LM5176QPWPRQ1 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.

LM5176QPWPRQ1 also features a programmable soft-start function and offers protection features including cycle-by-cycle current limiting, input undervoltage lockout (UVLO), output overvoltage protection (OVP), and thermal shutdown.

In addition, LM5176QPWPRQ1 features optional average input or output current limiting, optional spread spectrum to reduce peak EMI, and optional hiccup mode protection in sustained overload conditions.
