PI-2371-120198  
Simplifies Design - Reduces Time to Market  
Figure 1. Typical Application.  
• Integrated PWM Controller and high power MOSFET  
• Only one external capacitor needed for compensation,  
bypass and start-up/auto-restart functions  
Output Power Capability1-4  
System Level Fault Protection Features  
• Auto-restart and cycle by cycle current limiting functions  
handle both primary and secondary faults  
• On-chip latching thermal shutdown protects the entire  
system against overload

Description  
The TOPSwitch family implements, with only three terminals,  
all functions necessary for a DC to DC, converter: high voltage  
N-channelpowerMOSFETwithcontrolledturn-ongatedriver,  
voltagemodePWMcontrollerwithintegrated120kHzoscillator,  
high voltage start-up bias circuit, bandgap derived reference,  
bias shunt regulator/error amplifier for loop compensation and  
fault protection circuitry. Compared to discrete MOSFET and  
controllerorselfoscillating(RCC)switchingconvertersolutions,  
aTOPSwitchintegratedcircuitcanreducetotalcost,component  
count, size, weight and at the same time increase efficiency and  
system reliability. This device is well suited for Telecom,  
Cablecom and other DC to DC converter applications up to  
Table 1. TOP412/414 Output Power.  
Notes: 1. Assumes maximum junction temperature of 100 °C  
2. Assumes output of 5 V and KRP of 0.4 3. Soldered to 1 sq. inch  
(645 mm2), 2 oz. copper clad (610 gm/mm2) 4. The continuous  
power capability in a given application depends on thermal  
environment,transformerdesign,efficiencyrequired,inputstorage  
capacity, etc.  
21 W of output power. Internally, the lead frame of the  
SMD-8packageusessixofitspinstotransferheatfromthechip  
directly to the board, eliminating the cost of a heat sink.
