产品信息
TEA1733T/N1,118
交流/直流转换器 SW Mode Power Supply Controller 8-Pin GreenChip SMPS control IC
General description TEA1733T/N1,118
The TEA1738(L) is a low cost Switched Mode Power Supply (SMPS) controller IC
intended for flyback topologies. The TEA1738(L) 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.
Features TEA1733T/N1,118
„ SMPS controller IC enabling low-cost applications
„ Large input voltage range (12 V to 30 V)
„ Integrated OverVoltage Protection (OVP) on pin VCC
„ Very low supply current during start-up and restart (10 μA typical)
„ Low supply current during normal operation (0.55 mA typical without load)
„ Overpower or high/low line compensation
„ Adjustable overpower time-out
„ Adjustable overpower restart timer
„ Fixed switching frequency with frequency jitter to reduce EMI
„ Frequency reduction at medium power operation to maintain high efficiency
Applications TEA1733T/N1,118
„ All applications requiring efficient and cost-effective power supply solutions up to 75 W.
