Overview
PT1102 Step-down DC-DC Converter GENERAL DESCRIPTION The PT1102 is a CMOS-based fixed frequency step-down DC/DC converter with a built-in internal power MOSFET.
It achieves 1A continuous output current over a wide input supply range with excellent load and line regulation.
It requires a minimum number of readily available external components to complete a 1A step down DC to DC converter solution with low ripple and high efficiency.
The output voltage can be adjusted with external resisters.
With the enhanced voltage mode operation, the PT1102 achieves good loop stability with wide operating range.
Under light load conditions, the PT1102 automatically switches to a VFM mode to improve efficiency.
Fault condition protection includes current limiting and thermal shutdown.
Furthermore, the PT1102 has a built-in UVLO function that prevents the output from being unstable when the input voltage becomes too low.
The PT1102 is available in SOP8 packages.
