EC4230
Description
EC4230 is a pact, inductor-less, offline linear regulator. It steps down the AC line voltage to 3.3V/ 5V. It is a simple solution to provide a bias voltage in offline applications. EC4230 integrates a 500V power MOSFET, startup controller, voltage control circuit, AC synchronous circuit, low dropout regulator, etc. EC4230 also integrates smart control system uses AC line power when necessary, thus minimizing device losses to achieve good efficiency. EC4230 can help system designs meeting new standby power specifications. EC4230 integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), On Chip Thermal Shutdown (OTP), etc.
