Description

The SMP402, intended for non-isolated ISDN telecommunications power supply applications, combines high voltage power MOSFET switch with a switchmode power system controller in a monolithic integrated circuit. Few external components are required to implement a low cost power supply which meets stringent ISDN specifications. High frequency operation reduces total power supply size.

The P-channel power MOSFET switch features include high voltage, low RDS(ON), and low capacitance. Lower capacitance results in a reduction in gate drive power, and also facilitates higher frequency operation.
The controller section of the SMP402 contains all the blocks required to drive and control the power stage: start-up preregulator circuit, oscillator, bandgap reference, error amplifier, gate driver and level shift. Protection features include undervoltage lockout, thermal shutdown, and input polarity and level sensing.
The SMP402 is available in a 16-pin plastic SOIC package.
