AME7730

AME, Inc. AME7730 n General Description The AME7730 is a charge pump voltage doublers that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the AME7730 can deliver up to 100mA to the voltage regulated output. The AME7730 features very low output ripple and high efficiency over a large portion of its load range making this device ideal for battery-powered applications. Furthermore, the combination of few external components www.DataSheet4U.com and small package size keeps the total converter board area to a minimum in space restricted applications. The AME7730 contains a thermal management circuit to protect the device under continuous output short circuit conditions. The AME7730 is available in SOT-26 / TSOT-26 package and is rated from -40OC to 85OC. 100mA Regulated Charge Pump n Functional Block Diagram VIN φ2 CC+ φ1 φ1 φ2 VOUT φ1 φ2 EA EN Control GND n Features l l l l l l l l Input Voltage Range: 2.7V to 5V Accurate to with ±4% Output Current: 100mA with VIN >= 3.0V 50mA with VIN >= 2.7V 1MHz Switching Frequency Shutdown Mode < 1µA Short Circuit Protection Over Temperature Protection All AME's Lead Free Product Meet RoHS Standards n Typical Application C+ CFLY = 1µF 3.0V to 5V VIN VIN VOUT 5V / 100mA VOUT COUT=10µF AME 7730 GND CIN=10µF C- EN ON OFF n Applications l Cellular Phones l Digital Cameras l PDAs LCD displays l LED / Display Back Light Driver l LEDs for Comera Flash Rev.A.01 1 AME, In...
