Users Manual ISL95338EVAL1Z Users Manual: Evaluation Board Battery and Optical Rev.0.00 Jan 2018USERS MANUAL ISL95338EVAL1Z UG128 Rev.0.00 Evaluation Board Aug 17, 2017 1. Overview The ISL95338 is a bidirectional buck-boost voltage regulator, which provides bidirectional buck-boost voltage regulation and protection features. Intersils advanced R3 Technology is used to provide high light-load efficiency, fast transient response, and seamless DCM/CCM transitions. The ISL95338 takes input power from a wide range of DC power sources (conventional AC/DC ADPs, USB PD ports, travel ADPs, etc.) and safely converts it to a regulated voltage up to 24V. The ISL95338 also can convert a wide range DC power source connected at its output (system side) to a regulated voltage to its input (ADP side). This bidirectional buck-boost regulation feature makes its application very flexible. The ISL95338 includes various system operation functionalities such as Forward mode enable, Reverse mode enable, programmable soft-start time, and adjustable V , in both forward direction and reverse direction. The protection OUT functionalities include OCP, OVP, UVP, OTP, etc. 2 The ISL95338 has serial communication using SMBus/I C that allows programming of many critical parameters to deliver a customized solution. These programming parameters include, but are not limited to: output current limit, input current limit, and output voltage setting. 1.1 Key Features Bidirectional buck, boost, and buck-boost operation Input voltage range 3.8V to 24V (no dead zone) Output voltage up to 20V Up to 1MHz switching frequency Programmable soft-start time LDO output for VDD and VDDP System status alert function Bidirectional internal discharge function Active switching for negative voltage transitions Bypass mode in both directions Forward mode enable, Reverse mode enable OCP, OVP, UVP, and OTP protection 2 SMBus and auto-increment I C compatible 1.2 Specifications V = 3.8V to 24V (no dead zone) IN V = 2.4V to 20V OUT f = 1MHz maximum SW 1.3 Ordering Information Part Number Description ISL95338EVAL1Z ISL95338 buck-boost voltage regulator evaluation board UG128 Rev.0.00 Page 2 of 22 Aug 17, 2017
