Beschreibung
The RAA223021 evaluation board(RTKA223021DE0010BU) is a high voltage flyback converter that is designed to demonstrate a low-cost high performance isolated AC/DC conversion from a universal input of 85VAC to 265VAC, to a 12V output with the output current up to 1A.The board has a built-in overcurrent, short-circuit,input brownout and over-temperature protections, and is designed on a double side Printed Circuit Board (PCB) with a full-wave input rectification. It is precompliant with the conducted EMI requirements by EN55022/CISPR 22. The RTKA223021DE0010BU uses the RAA223021 SOIC-7 packaged IC.
Eigenschaften
- Ultra-low standby power (<20mW)
- No audible noise
- Low quiescent current (<80µA)
- Output voltage as low as 3.3V
- Low EMI with frequency dithering
- 7 Ld SOIC package ▪ Programmable PFM allows optimization of COUT for various standby power requirements
- Protection features: Short-Circuit Protection (SCP), Overload Protection (OLP), Overvoltage Protection (OVP), open feedback protection, and Over-Temperature Protection (OTP).
Typische Anwendungen
- Home appliances, Home automation,IoT,and sensors, Metering and Industry control.
- Bias power
