Control IC 8-Pin SO T/R

The GreenChip II is the second generation of controller ICs intended for green flyback Switched Mode Power Supplies (SMPS). Its high level of integration allows the design of a cost effective power supply with a very low number of external components. The TEA1532BT; TEA1532CT can also be used in fixed frequency, Continuous Conduction Mode (CCM) converter designs for low voltage and high current applications. At low power (standby) levels the system operates in cycle skipping mode which minimizes the switching losses during standby.

• Universal mains supply operation (70 V to 276 V AC)
• High level of integration, resulting in a very low external component count
• Fixed frequency Continuous Conduction Mode (CCM) operation capability
• Quasi-Resonant (QR) Discontinuous Conduction Mode (DCM) operation capability
• Valley or zero voltage switching for minimum switching losses in QR operation
• Cycle skipping mode at very low loads
• On-chip start-up current source
• Safe restart mode for system fault conditions
• Zero current switch-on in QR mode
• Undervoltage protection (foldback during overload)
• IC OverTemperature Protection (OTP) (latched)
• Low and adjustable OverCurrent Protection (OCP) trip level
• Soft (re)start
• Mains voltage-dependent operation-enabling level
• Brown-out protection
• General purpose input for latched or safe restart protection and timing
