Description :
This power module is an isolated-type industrial level power module that can be used in AC-DC power converting. When the situations of over voltage, over current and short circuit appear, this module will help to protect whole device by locking up. What’s more, It can realize isolating the high and low voltage and support AC 90-265V input and DC 5V output. Its master chip is high-performance, low-power consumption IW1700 (no-load power consumption less than 5mW).
Feature
- Intelligent low power management achieves ultra-low operating current at no-load
- Adaptive load transient detection and fast response
- Low 1.7uA Start-Up Current
- Optimized 72 kHz maximum PWM switching frequency achieves best size and effi ciency
- Adaptive multi-mode PWM/PFM control improves efficiency
- Direct drive of low-cost BJT switch
- Built-in current sense resistor short circuit protection
