Additional Infomation About Product

TEA1738GT GreenChip SMPS control IC Rev. 1 2 September 2011 Product data sheet 1. General description The TEA1738GT is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in peak current and frequency control mode. Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1738GT IC includes OverPower Protection (OPP). This enables the controller to operate under overpower situations for a limited amount of time. Two pins, VINSENSE and PROTECT, are reserved for protection purposes. Input UnderVoltage Protection (UVP), output OverVoltage Protection (OVP) and OverTemperature Protection (OTP) can be implemented using a minimal number of external components. At low power levels the primary peak current is set to 25 % of the maximum peak current and the switching frequency is reduced to limit switching losses. The combination of fixed frequency operation at high output power and frequency reduction at low output power provides high efficiency over the total load range. The TEA1738GT enables low cost, highly efficient and reliable supplies for power requirements up to 75 W to be designed easily and with a minimum number of external components. The TEA1738GT is intended to operate in combination with a standby power supply. It has a lower start-up voltage than the TEA1738. 2. Features and benefits 2.1 Features SMPS controller IC enabling low-cost applications Large input voltage range (12 V to 30 V) Integrated OverVoltage Protection on pin VCC Very low supply current during start-up and restart (10 A typical) Low start-up voltage (13.2 V typical) Low supply current during normal operation (0.55 mA typical no load) Overpower or high/low line compensation Adjustable overpower time-out Adjustable overpower restart timer Fixed switching frequency with frequency jitter to reduce EMITEA1738GT NXP Semiconductors GreenChip SMPS control IC Frequency reduction at medium power operation to maintain high efficiency Frequency reduction with fixed minimum peak current at low power operation to maintain high efficiency at low output power levels Frequency increase at peak power operation Slope compensation for CCM operation Low and adjustable OverCurrent Protection (OCP) trip level Adjustable soft start Two protection inputs (e.g. for input UVP and OTP) IC overtemperature protection 3. Applications All applications requiring efficient and cost-effective power supply solutions up to 75 W. 4. Ordering information Table 1.
