PT1311 Datasheet (PowTech) - High Efficiency Synchronous Boost DC/DC Converter

PT1311, High Efficiency Synchronous Boost DC/DC Converter

The PT1311 is a high efficiency synchronous fixed frequency step-up DC/DC converter.

The device is available in an adjustable version and fixed output voltages of 3.3V or 5.0V.

Supply current during operation is only 25μA and drops to ≤1μA in shutdown.

The 0.85V to 4.2V input voltage range makes the
