The LM5175QPWPRQ1 is a synchronous four-switch buck-boost DC/DC controller manufactured by Texas Instruments. It can operate over a wide input voltage range from 3.5V to 42V (up to 60V), supporting a wide range of applications. The LM5175QPWPRQ1 is controlled in current mode in both buck and boost operating modes to provide excellent load and line regulation performance.
The switching frequency can be programmed with an external resistor and synchronized with an external clock signal. The device also features programmable soft start and offers protection features such as cycle by cycle current limit, input undervoltage lock (UVLO), output overvoltage protection (OVP), and thermal shutdown.
In addition, the LM5175QPWPRQ1 features selectable continuous on-mode (CCM) or intermittent on-mode (DCM), selectable average input or output current limits, selectable spread spectrum to reduce peak electromagnetic interference (EMI), and selectable intermittent mode protection against persistent overload.
