24Vin to 12Vout @ 100mA isolated push-pull reference design with cascode FETs
Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 24 V |
| Output 1 | 12 V / 0.1 A |
| IC revision | B |
Description
This reference design extends the input voltage range on low-voltage push-pull controllers by employing cascode external FETs. The input voltage range is 12 V (+/-10%) or 24 V (+/-10%), with an output power of 1.2 W. The output voltage can be selected from two values, 12 V and 5 V, according to a list of four transformers.
Features
- Low-cost solution, allowing high voltage isolation and low noise
- No loop compensation (open loop)
- Typical application: isolated gate driver power supply
Typical applications
- AC analog input module, Multifunction relay, Processor module, Wired communication modules
