65 mm pitch ), 24pin Plastic Shrink Small Outline Package (SSOP Type) DESCRIPTION AN33014UA is 1-channel DC-DC Step down Regulator integrated N-channel Power MOSFET and employs the voltage mode switching control system.
This IC can be operated with wide input voltage range and is build in several protection functions, so this IC can provide high reliability power supply system.
Since it is possible to use up to 1 MHz switching frequency and it is unnecessary to add external parts for High Side Switch, this IC realizes downsizing of set and reducing in the number of external parts.
For USB applications, this IC can controlled USB supplied voltage level with external resistor for USB load current monitor (Current Feedback Function), and it can provide suitable power supply system for external USB with no voltage drop due to USB cable loss.
Maximum current is 1.
5 A.
APPLICATIONS High Input Voltage Power Systems for USB such as ・Car-Audio system ・Car-Navigation system ・OA Equipment ・Home Appliances etc.
SIMPLIFIED APPLICATION VREG or EXT Power E...
