CE8331

High Power 1MHz External Power MOSFET Boost Controller CE8331 Series „ INTRODUCTION: The CE8331 is a external power MOSFET boost controller designed for single-cell lithium or two cell alkaline, NiMH, or NiCd battery powered applications. A switching frequency of 1.0MHz minimizes solution footprint by allowing the use of tiny, low cost and low profile inductor and ceramic capacitors. The current mode PWM design is internally compensated. The CE8331 is rated over the -40°C to +85°C temperature range. „ FEATURES: z 1.0MHz Switching Frequency z PWM/PFM Auto Switching Maintains High Efficiency Overall Load Current Range z 600mV Feedback Voltage z Over-Thermal Protection z 88% efficiency @ Output 5V/2.5A Input 3.3V z 86% efficiency @ Output 5V/3.0A Input 3.3V z Ceramic Capacitor Compatible z Tiny SOT23-6L Package „ APPLICATIONS： z Back-up Battery Charger z Tablet PC z 3G/4G Wireless Routers z Mobile Internet Device z Networking card powered from PCI „ PIN CONFIGURATION: „ ORD...
