TEA18362T数据手册恩XP中文资料规格书

描述 Description

The TEA18362T is a controller IC for low-cost Switched Mode Power Supplies (SMPS). Itis intended for DCM / QR flyback topologies. The built-in green functions provide high efficiency at allpower levels.

特性 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
• 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 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
• 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)
