PT1322-SOT23-6,1MHz,2A Step-up DC/DC Converter


PT1322-High Efficiency 1MHz,2A Step-up DC/DC Converter  DataSheet

GENERAL DESCRIPTION
    The PT1322 is a highly efficiency, current mode control step-up DC/DC converter with an integrated 120mΩ RDS(ON) N-channel MOSFET. The fixed 1MHz switching frequency and internal compensation circuitry reduce external component count and save the PCB space. The built-in internal soft-start circuitry minimizes the inrush current at start-up. The PT1322 is available in SOT23-6 package.

FEATURES
 Input Voltage Operating Range: 2.7 V to 5.5 V
 1MHz Constant Frequency Operation
 Minimum on time: 100ns typical
 Minimum off time: 100ns typical
 Maximum output voltage: 6V
 Low RDS(ON): 120mΩ
 SOT23-6 Package

APPLICATIONS
 Cell Phone and Smart Phone
 PDA, PMP, MP3
 Digital Still Cameras
