Vishay Siliconix  
500 mA - Fixed Output Boost Converter for Single or Dual Cell  
DESCRIPTION  
FEATURES  
Voltage mode control with internal frequency  
compensation  
SiP12502 is a boost converter IC with fixed output voltage for  
single or double cell NiMH or Alkaline battery pack. Featuring  
with an internal low resistance power MOSFET, it is capable  
of starting up with a low battery voltage of 0.85 V. It only  
needs four external components (an inductor, a diode and  
two capacitors) to construct a step-up converter. For best  
efficiency performance, it is designed to operate in PWM  
mode with a 300 kHZ switching frequency under normal load  
and in PFM mode under light load. The voltage-mode control  
loop is internally compensated, simplifying converter design  
and reducing external parts count. It accepts input voltages  
from 0.85 V to 5 V, providing fixed output voltages of 2.0 V,  
3.3 V, and 5.0 V. It also features low shutdown current of  
under 1 µA, over voltage protection, thermal shutdown  
protection, a power good output and antiringing control to  
minimize EMI.  
0.85 V to 5.0 V input voltage range  
Fixed output voltage options - 2.0 V, 3.3 V, and 5.0 V  
Other voltages available upon request  
PWM control with 300 kHz fixed switching frequency  
PFM control for light load  
Powered from the output voltage supply  
Integrated UVLO and soft-start  
Logic controlled shutdown (< 1 µA)  
85 % typical efficiency  
Internal power MOS switch: 0.2 Ω at 3.3 V output  
Antiringing switch to minimize EMI  
Power good output  
Shutdown input  
Minimum external components  
PowerPAK® MLP33-6 package, (DFN-6, 3 x 3)  
Over voltage protection  
SiP12502 is available in a lead (Pb)-free 6-pin, PowerPAK  
MLP33 package and is specified to operate over the  
industrial temperature range of - 40 °C to 85 °C.
