High Efficiency 1MHz, 1.5A Boost Regulator
CE8310 Series
INTRODUCTION:
The CE8310 is designed for single-cell or
dual-cell or triangle-cell alkaline, NiMH, or NiCd or
single-cell lithium-ion battery powered application.
It is a high efficiency boost converter with 600mV
feedback voltage. A switching frequency of
1.0MHz minimizes solution footprint by allowing
the use of tiny low profile inductors and ceramic
capacitors. The current mode PWM design is
internally compensated, and the device has a
0.9V start-up voltage with operation down to 0.65V.
The CE8310 is rated over the -40°C to +85°C
temperature range.
FEATURES:
V
