Datasheet ISL95338 Bidirectional Buck-Boost Voltage Regulator The ISL95338 is a bidirectional, buck-boost voltage Features regulator that provides buck-boost voltage regulation Bidirectional buck, boost, and buck-boost operation and protection features. The Renesas advanced R3 Input voltage range: 3.8V to 24V (no dead zone) Technology provides high light-load efficiency, fast transient response, and seamless DCM/CCM Output voltage: up to 20V transitions. Up to 1MHz switching frequency The ISL95338 takes input power from a wide range of Programmable soft-start time DC power sources (such as conventional AC/DC ADPs, USB PD ports, and travel ADPs) and safely LDO output for VDD and VDDP converts it to a regulated voltage up to 20V. The System status alert function ISL95338 can also convert a wide range DC power Bidirectional internal discharge function source connected at its output (system side) to a regulated voltage to its input (ADP side). This Active switching for negative voltage transitions bidirectional buck-boost regulation feature makes its Bypass mode in both directions application very flexible. Forward mode enable, Reverse mode enable The ISL95338 includes various system operation OCP, OVP, UVP, and OTP protection functions such as Forward mode enable, Reverse mode enable, programmable soft-start time, and 2 SMBus and auto-increment I C compatible adjustable V in both the forward direction and OUT Pb-free (RoHS compliant) reverse direction. The protection functionalities include OCP, OVP, UVP, and OTP. 32 Ld 4x4 TQFN Package The ISL95338 has serial communication through Applications 2 SMBus/I C that allows programming of many critical Tablets, Ultrabooks, power banks, mobile devices, parameters to deliver a customized solution. These and USB-C programming parameters include, but are not limited to: output current limit, input current limit, and output voltage setting.
