台湾致新 G2263AV1U AQFN2X2-14 代理商主推

　　General Description

　　The G2263 is a high efficiency, synchronous,

　　current-mode, boost converter with output disconnect.

　　The G22263 starts up from and input voltage as low as

　　1.9v, and maintains good performance with input

　　voltage higher than 2.8V. The integrated P-channel

　　synchronous rectifier improves efficiency and eliminated

　　the need for an external Schottky diode. This P-channel

　　disconnects the output from the input during shutdown.

　　The G2263 provides a compact solution for a 5V output,

　　4A load requirement, using a supply voltage down to

　　2.8V.

　　The G2263 is available in AQFN2x2-14 package.

　　Features

　　2.4V ~ 5.5V Input Voltage Operation.

　　98% Efficient DC/DC Converter

　　600kHz Fixed Switching Frequency

　　9A Typical Switch Current Limit

　　40uA Quiescent Current

　　High Efficiency over Full Load Range

　　Internal Soft-start and Compensation

　　True Output Load Disconnect from Input

　　Built-In OCP, SCP, OVP and OTP Protection

　　AQFN2X2-14 Package.
