the tcp8510 is a synchronous four-switch buck-boost dc/dc controller capable of regulating the output voltage at, above, or below the input voltage. the tcp8510 operates over a wide input voltage range of 4.5 v to 40 v to support a variety of applications.
the tcp8510 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. this 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.
the tcp8510 is available in a qfn4x4-24l package, provides a very compact system solution and good thermal conductance.
