500 mA - Fixed Output Boost Converter for Single or Dual Cell
DESCRIPTION
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.
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.
