PL5501 Description
PL5501 is a synchronous 4-switch Buck-Boost controller capable of regulating the output voltage at above or below the input voltage. PL5501 operates over a wide input voltage range of 3.6 V to 32 V (36 V maximum) to support a variety of applications. PL5501 employs Constant ON time control in buck, boost and buck-boost operation modes for superior load and line regulation.
