DPA-Switch Family

Highly Integrated DC-DC Converter ICs

for Distributed Power Architectures

Product Highlights

Highly Integrated Solution

• Eliminates 20-50 external components–saves space, cost

• Integrates 220 V high frequency MOSFET, PWM control

• Lower cost plastic DIP surface mount (G package) and

CIRCUIT

Superior Performance and Flexibility

• Eliminates all external current sensing circuitry

• Built-inauto-restartforoutputoverload/openloopprotection

• Pin selectable 300/400 kHz fixed frequency

PI-2770-032002

• Wide input (line) voltage range: 16-75 VDC

• Source connected tab reduces EMI

Figure 1. Typical Forward Converter Application.

• Line under-voltage (UV) detection: meets ETSI standards

• Line overvoltage (OV) shutdown protection

• Low cost synchronous rectification: line UV/OV shut down

limits gate drive voltage range from transformer winding

• Fully integrated soft-start for minimum stress/overshoot

• Externally programmable current limit

• Supports forward or flyback topology

• Cycle skipping: regulation to zero load without pre-load

• Hysteretic thermal shutdown for automatic fault recovery

Description

Table 1. Notes: 1. Maximum output power is limited by device internal

current limit. 2. See Applications Considerations section for complete

description of assumptions and for output powers with other input voltage

ranges. 3. For device dissipation of 1.5 W or below, use Por G packages.

Device dissipation above 1.5 W is possible only with R package. 4. See

Part Ordering Information. 5. Due to higher switching losses, the DPA425

may not deliver additional power compared to a smaller device.

The DPA-Switch IC family introduces a highly integrated

solution for DC-DC conversion applications in the 16-75 VDC

input range.

DPA-Switch uses the same proven topology as TOPSwitch, cost

effectively integrating the high voltage power MOSFET, PWM

control, fault protection and other control circuitry onto a single

CMOS chip. High performance features are enabled with three

user configurable pins.

The following transparent or built-in features are also provided:

soft-start, cycle skipping down to zero load and hysteretic

thermal shutdown. In addition, all critical parameters (i.e.

current limit, frequency, PWM gain) have tight temperature

and absolute tolerance, to simplify design and optimize system

cost.
