TEA1532BT - NXP Semiconductors

TEA1532BT (TEA1532BT / TEA1532CT) GreenChip II SMPS control IC

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 desig.

Features
