TOP412/414

TOPSwitch^®Family

Three-terminal DC to DC PWM Switch

Product Highlights

Low Cost Replacement for Discrete Switchers

• Up to 15 fewer components - cuts cost, increases reliability

• Allows for a smaller and lighter solution under 12 mm

height, all surface mount components

Over 80% Efficiency in Flyback Topology

• Built-in start-up and current limit reduce DC losses

• Low capacitance MOSFET cuts switching losses

• CMOS controller/gate driver consumes only 7 mW

• 70% maximum duty cycle minimizes conduction losses

CONTROL

TOP414

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 Capability^1-4

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 K_RPof 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
