RDR-839 – 12 W Power Supply for Appliances Using TinySwitch-4
12 W Power Supply for Appliances (85 VAC – 265 VAC input; 12 V, 1 A output) using TinySwitch-4 (TNY288PG) Summary and Features
– EcoSmart– meets all existing and proposed energy efficiency standards including ErP.
– No-load consumption <30 mW; more than 300 mW available in stand-by with
500 mW input
> 84% average active-mode efficiency – DOE6 and EC CoC (v5)
The board can fit P/G or the cost-effective D package
BP/M capacitor value selects power MOSFET current limit for greater design flexibility
Accurate detection output overvoltage protection (OVP) using primary bias winding sensed
shutdown feature
Accurately toleranced I2f parameter (-10%, +12%) reduces system cost
Increases MOSFET and magnetics power delivery
Reduces overload power, which lowers output diode and capacitor costs
Integrated TinySwitch-4 safety / reliability features
Accurate (±5%), auto-recovering, hysteretic thermal shutdown function maintains safe
PCB temperatures under all conditions
Auto-restart protects against output short-circuit and open loop fault conditions
P and G package with >3.2 mm creepage on package enables reliable operation in high
humidity and high pollution environments
Meets EN550022 and CISPR-22 Class B conducted EMI with >12 dBµV margin
Meets IEC61000-4-5 Class 3 AC line surge
