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

IN

Operation Range: 0.65V to 6.0V

 600mV Feedback Voltage

 Output Current 1.5A@VIN≧3.2V

 Up to 90% Efficiency

 Low Start-Up Voltage: 0.9V@Io=1mA

 Low Hold Voltage: 0.75V@Io=1mA

 1.0MHz Fixed Switching Frequency

 PWM/PFM Auto Switching Maintains High

Efficiency

 Over-Thermal and Over-Current Protection

 Low Shutdown Current: <1.0μA

 APPLICATIONS:

 Back-up Battery Charger

 Tablet PC

 3G/3.5G Wireless Routers

 Mobile Internet Device

 Networking card powered from PCI or

PCI-express slots
