High-
Voltage PWM Power-Supply Controller
MAX5003
General Description
The MAX5003 high-
voltage switching power-supply controller has all the features and building blocks needed for a cost-effective flyback and forward
voltagemode control converter.
This device can be used to design both isolated and nonisolated power supplies with multiple output
voltages that operate from a wide range of
voltage sources.
It includes a high-
voltage internal start-up circuit that operates from a wide 11V to 110V input range.
The MAX5003 drives an external Nchannel power
MOSFET and has a current-sense pin that detects overcurrent conditions and turns off the power ...
