Short-Form Datasheet  
RAA489800  
Bidirectional Buck-Boost Voltage Regulator  
The RAA489800 is a bidirectional, buck-boost voltage  
regulator that provides buck-boost voltage regulation  
and protection features. The advanced Renesas  
R3™ Technology provides high light-load efficiency,  
fast transient response, and seamless DCM/CCM  
transitions.  
Features  
Bidirectional buck, boost, and buck-boost operation  
Configurable for 4-switch buck-boost or 2-switch  
buck operation  
Input voltage range: 3.8V to 23V (no dead zone)  
Output voltage: up to 21V  
The RAA489800 takes input power from a wide range  
of DC power sources up to 23V (such as conventional  
AC/DC adapters (ADP), USB PD ports, travel ADP)  
and safely converts it to a regulated voltage up to  
21V. The RAA489800 can also 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 the RAA489800’s application very flexible. In  
addition to 4-switch buck-boost configuration, it can  
also support 2-switch Buck mode operation.  
Up to 1MHz switching frequency  
Pin programmable soft-start time  
LDO output for VDD and VDDP  
System FAULT status ALERT function  
Input/output internal discharge function  
Active switching for negative voltage transitions  
Pass Through mode in both directions  
Forward and Reverse mode enable pins  
OCP, OVP, UVP, and OTP protection  
Absolute overvoltage protection  
The RAA489800 includes various system operation  
functions such as the Forward mode enable pin,  
Reverse mode enable pin, programmable soft-start  
2
SMBus and auto-increment I C compatible  
time, and adjustable forward and reverse V  
. It also  
Pb-free (RoHS compliant)  
OUT  
has forward and reverse power-good indicators. The  
protection functionalities include OCP, OVP, UVP, and  
OTP.  
32 Ld 4x4 TQFN package  
UL 2367, IEC 62368-1: File No. E520109  
Applications  
The RAA489800 has serial communication through  
2
SMBus/I C that allows programming of many critical  
Tablets, Ultrabooks, power banks, mobile devices,  
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.  
and USB-C
