Panasonic AN3301X Step-Down Regulators

Panasonic AN3301X series Step-Down Regulators feature a highly reliable DC/DC step-down regulator that employs a voltage control system. These Panasonic devices can be operated at a high voltage range (from 5V to 39V) and can also be used for power supply LSI of car-AV systems. These new AN3301X parts have an external clock synchronous function up to 2MHz as well as PLL technology allowing control switching frequency without output voltage malfunction. By integrating a high side SW solution and flag function, the AN3301X Series can provide a suitable power supply system for an external USB. AN3301X Series Step-Down Regulators also include 2ch-external FET type, 1ch-internal FET type, and 1ch-internal FET type with load current feedback function that compensates the output voltage drop. These Panasonic devices are ideal for use in automotive, office automation, and home appliance applications.
