TEA1532BT - (TEA1532BT / TEA1532CT) GreenChip II SMPS control IC

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.

Key Features

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.
