The TEA18362LT/1J is a controller IC for low-cost Switched Mode Power Supplies (SMPS).It is intended for DCM / QR flyback topologies. The built-in green functions provide high efficiency atall power levels.
Feature
- SMPS controller IC for low-cost applications
- Large supply voltage range (up to 30 V)
- Integrated high-voltage start-up
- Continuous VCC regulation during start-up and protection via the HV pin, allowing a minimum VCC capacitor value
- Reduced opto current in burst mode enabling low no-load power consumption
- Operating frequencies in all operating modes are outside the audible area
- Integrated X-capacitor discharge
- Adjustable soft start
- Power-down mode via the PROTECT pin
- Low supply current during normal operation (0.6 mA without load)
- Low supply current during non-switching state in burst mode (0.2 mA)
- Valley switching for minimum switching losses
- Frequency reduction with fixed minimum peak current to maintain high efficiency at low output power levels
- Mains voltage independent OverPower Protection (OPP)
- OverTemperature Protection (OTP)
- Integrated overpower time-out
- Continuous mode protection using demagnetization detection
- Accurate OverVoltage Protection (OVP)
- General-purpose input for latched protection; for use with system OverTemperature Protection (OTP)
