Data Short To request the full datasheet, visit the RAA489800 product page. RAA489800 Bidirectional Buck-Boost Voltage Regulator The RAA489800 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 advanced Renesas R3 Configurable for 4-switch buck-boost or 2-switch Technology provides high light-load efficiency, fast buck operation transient response, and seamless DCM/CCM transitions. Input voltage range: 3.8V to 23V (no dead zone) The RAA489800 takes input power from a wide range Output voltage: up to 21V of DC power sources up to 23V (such as conventional Up to 1MHz switching frequency AC/DC adapters (ADP), USB PD ports, travel ADP) and safely converts it to a regulated voltage up to 21V. Pin programmable soft-start time The RAA489800 can also convert a wide range DC LDO output for VDD and VDDP power source connected at its output (system side) to System FAULT status ALERT function a regulated voltage to its input (ADP side). This bidirectional buck-boost regulation feature makes the Input/output internal discharge function RAA489800s application very flexible. In addition to Active switching for negative voltage transitions 4-switch buck-boost configuration, it can also support Pass Through mode in both directions 2-switch Buck mode operation. Forward and Reverse mode enable pins The RAA489800 includes various system operation functions such as the Forward mode enable pin, OCP, OVP, UVP, and OTP protection Reverse mode enable pin, programmable soft-start Absolute overvoltage protection time, and adjustable forward and reverse V . It also OUT 2 has forward and reverse power-good indicators. The SMBus and auto-increment I C compatible protection functionalities include OCP, OVP, UVP, and Pb-free (RoHS compliant) OTP. 32 Ld 4x4 TQFN package The RAA489800 has serial communication through 2 SMBus/I C that allows programming of many critical Applications parameters to deliver a customized solution. These Tablets, Ultrabooks, power banks, mobile devices, programming parameters include, but are not limited and USB-C to: output current limit, input current limit, and output voltage setting.
