Product Details

Block Diagram


TEA18363 Block Diagram


General features

  • 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; NXP Semiconductors patented (Patent reference: 81512184EP01 (Patent pending))
  • Adjustable soft start
  • Power-down mode via the PROTECT pin1

Green features

  • Low supply current during normal operation (0.6 mA without load)
  • Low supply current during the 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

Protection features

  • Mains voltage independent OverPower Protection (OPP)
  • OverTemperature Protection (OTP)
  • Integrated overpower time-out
  • Integrated restart timer for system fault conditions
  • Continuous mode protection using demagnetization detection
  • Accurate OverVoltage Protection (OVP)
  • General-purpose input for latched protection; for use with system OverTemperature Protection (OTP)
  • Driver maximum on-time protection

Part numbers include: TEA18363T, TEA18363LT.
