RT8208A/B  
Programmable Output Voltage Single Synchronous  
Buck Controller  
General Description  
Features  
z Ultra-High Efficiency  
The RT8208A/B is a constant-on-time PWM controller  
which provides four resistor programmable DC output  
voltages by controlling the G0 and G1 digital input. The  
output voltage is programmable from 0.75V to 3.3V. The  
RT8208A/B offers the lowest total solution cost in systems  
where need output voltage slewing. The RT8208A/B  
provides an automatic masking power good output during  
output voltage transition.  
z Resistor Programmable Output Voltage from 0.75V  
to 3.3V with Integrated Transition Support  
z Quick Load Step Response within 100ns  
z 1% VFB Accuracy over Line and Load  
z 4.5V to 26V Battery Input Range  
z Resistor Programmable Frequency  
z Integrated Bootstrap Switch  
z Resistor Programmable Positive Current Limit by  
Low Side RDS(ON) Sense (Lossless Limit)  
z Negative Current Limiter  
The constant-on-time PWM control scheme handles wide  
input/output ratios with ease and provides 100ns “instant-  
on” response to load transient while maintaining a  
relatively constant frequency. It provides the high efficiency,  
excellent transient response, and DC output accuracy  
needed for stepping down high voltage batteries to  
generate low voltage CPU core, graphics, I/O and chipset  
RAM supplies in notebook computers.  
z Voltage Transient Overshoot Eliminator*  
z Over Voltage Protection  
z Under Voltage Protection  
z 4 Steps Current Limit During Soft-Start  
z Power Good Indicator  
z RoHS Compliant and Halogen Free  
* Paten Pending  
The RT8208A/B achieves high efficiency at a reduced cost  
by eliminating the current sense resistor in traditional  
current mode PWMs. Efficiency is further enhanced by  
its ability to drive very large synchronous rectifier  
MOSFETs. The buck conversion allows this device to  
directly step down from high voltage batteries for the highest  
possible efficiency. Additional features include soft-start,  
under voltage protection, programmable over current  
protection and non-overlapping gate drive. The RT8208A/  
B is available in a WQFN-16L 3x3 package.  
Applications  
z Notebook Computers  
z System Power Supplies  
z I/O Supplies  
z Programmable-Output Power Supplies
