SC419  
EcoSpeedTM DC-DC Converter  
with Integrated Boost Diode  
POWER MANAGEMENT  
Features  
Description  
Power system  
The SC419 is a synchronous buck power supply controller.  
It features a bootstrap switch in a space-saving MLPQ-  
3 x 3mm 20-pin package. The device is highly efficient  
and uses minimal PCB area. It uses pseudo-fixed frequency  
adaptive on-time operation to provide fast transient  
response.  
Input voltage — 3V to 28V  
Integrated bootstrap switch  
1% reference tolerance -40 to +85 °C  
EcoSpeedTM architecture with pseudo-fixed fre-  
quency adaptive on-time control  
Internal soft-start and soft-shutdown at output  
SmartDriveTM  
The SC419 supports using standard capacitor types such  
as electrolytic or special polymer in addition to ceramic, at  
switching frequencies up to 1MHz. The programmable  
frequency, synchronous operation, and programmable  
power-save provide high efficiency operation over a wide  
load range.  
Logic input/output control  
Independent control EN for LDO and switcher  
Programmable VIN UVLO threshold  
Power good output  
Selectable power save mode  
Programmable ultrasonic power save mode  
Protections  
Additional features include cycle-by-cycle current limit,  
soft-start, under and over-voltage protection, program-  
mable over-current protection, soft shutdown, selectable  
power-save modes, and programmable ultra-sonic power-  
save. The device also provides an enable input and a  
power good output, useful for sequencing multiple  
devices.  
Over-voltage/under-voltage  
TC compensated RDS(ON) sensed current limit  
Thermal shutdown  
Smart power save  
Output capacitor types  
High ESR — SP, POSCAP, OSCON  
Ceramic capacitors  
The input voltage can range from 3V to 28V. The wide  
input voltage range and programmable frequency make  
the device extremely flexible and easy to use in a broad  
range of applications. Support is provided for single cell  
or multi-cell battery systems in addition to traditional DC  
power supply applications.  
Package — 3 x 3mm, 20-pin MLPQ  
Lead-free and halogen free  
RoHS and WEEE compliant
