DPA-Switch™ IC Family | Integrated DC-DC Conversion Solution

The DPA-Switch™ family is a highly integrated IC solution designed for DC-DC conversion applications operating from a 16–75 VDC input range. Based on the proven TOPSwitch™ topology, the DPA-Switch integrates a power MOSFET, PWM control, fault protection, and essential control circuitry onto a single CMOS chip.

This cost-effective integration reduces system complexity and overall BOM cost while delivering high efficiency and reliability.

Key Features:

• Wide Input Voltage Range: 16 VDC to 75 VDC

• Integrated Functions: Power MOSFET, PWM control, fault protection, thermal shutdown

• Three user-configurable pins for application flexibility

• Tight tolerance control of current limit, frequency, and PWM gain

• Hysteretic thermal shutdown for enhanced safety and reliability

• Reduced component count & system cost with single-chip integration

Applications:

• Distributed power architectures

• Telecom & networking equipment

• Industrial power supplies

• Automotive and transportation systems

• High-reliability DC-DC conversion

Package Options:

• G Package: SMD-8

• P Package: DIP-8
