The SMP402, intended for non-isolated ISDN  
telecommunications power supply applications, combines a  
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  
powersupplywhichmeetsstringentISDNspecifications. High  
frequency operation reduces total power supply size.

Figure 2. Pin Configuration.  
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 pre-  
regulator circuit, oscillator, bandgap reference, error amplifier,  
gate driver and level shift. Protection features include  
undervoltage lockout, thermal shutdown, and input polarity  
and level sensing.
