PeakSwitch™ Family

Product catalog summary

Product Highlights

Simple ON/OFF control without the need for loop compensation.
Capable of delivering peak power up to three times the maximum continuous output power.
Operates at 277 kHz during peak power to reduce transformer size.
Features tight I2f tolerances and minimal temperature variation for easier design and cost reduction.
Adaptive switching cycle on-time extension increases low line peak output power, minimizing bulk capacitor size.
High bandwidth ensures fast turn-on with no overshoot and excellent transient load response.

High Performance at Low Cost

Suitable for applications with large peak to continuous load ratio requirements.
Programmable smart AC line sensing for latching shutdown during faults.
Adaptive current limit reduces output overload power.
Accurate hysteretic thermal shutdown with automatic recovery for system-level overload protection.
Low component count for higher reliability and single-side PCB.
Frequency jittering reduces EMI filter cost.

EcoSmart® - Energy Efficiency

Exceeds California Energy Commission, ENERGY STAR, and EU requirements.
No-load consumption is less than 200 mW at 265 VAC input.
Standby output power is ≥0.6 W for 1 W input power.
Sleep mode power is ≥2.4 W at 3 W input.

Design Tools and Support

Data Sheet, Application Note, Engineering Report, and Design Idea available for download.
PI Expert™ Suite for power supply design, including transformer design.
Reference Design (DAK-93) includes a power supply, sample devices, unpopulated PCB, data sheet, and engineering report.

Operation and Design Highlights

Configured as a flyback converter with an internal oscillator frequency of 277 kHz.
Feedback from the output regulates the output voltage by skipping MOSFET switching cycles.
Capable of delivering peak power pulses up to 81 W for up to 50 ms while maintaining output voltage regulation.
Key design points include setting the reset time of the latched shutdown function and thermal considerations for the PeakSwitch IC and components.
