PowTech PT1322
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 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 internal soft-start circuitry minimizes the inrush current at start-up.| Part No. | PT1322 |
