General description
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.
The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates in cycle skipping mode with valley detection.
The proprietary high voltage BCD800 process makes direct start-up possible from the rectified universal mains voltage in an effective and energy efficient way. A second low voltage, Bipolar CMOS (BICMOS) IC is used for accurate, high speed protection functions and control.
The TEA1532BT; TEA1532CT enables highly efficient and reliable supplies to be designed easily.
Features
Distinctive features
- 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)
Green features
- Valley or zero voltage switching for minimum switching losses in QR operation)
- Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for a typical adapter application)
- On-chip start-up current source)
Protection features
- Safe restart mode for system fault conditions)
- Zero current switch-on in QR mode)
- Undervoltage protection (fold back during overload))
- IC OverTemperature Protection (OTP) (latched))
- Low and adjustable OverCurrent Protection (OCP) trip level)
- Soft (re)start)
- Mains voltage-dependent operation-enabling level)
- TEA1532CT: general purpose input for latched or safe restart protection and timing, e.g. to be used for OverVoltage Protection (OVP), output short-circuit protection or system OTP)
- TEA1532BT: general purpose input for latched protection and timing, e.g. to be used for OVP, output short-circuit protection or system OTP)
- Brown-out protection)
