Analog Devices MAX17690 | Demoboard MAXREFDES1095
Miniature, 12V/500mA, Synchronous, No-Opto Flyback DC-DC Converter with 92.8% Efficiency
Overview
| Topology | Flyback Converter |
| Input voltage | 18-60 V |
| Output 1 | 12 V / 0.5 A |
Description
The MAX17690 implements an innovative algorithm toaccurately determine the output voltage by sensing thereflected voltage across the primary winding during theflyback time interval. By sampling and regulating thisreflected voltage when the secondary current is close tozero, the effects of secondary-side DC losses in the transformerwinding, the PCB tracks, and the rectifying diodeon output voltage regulation can be minimized.The MAX17690 also compensates for the negative temperaturecoefficient of the rectifying diode.
