TEA1731LTS - NXP

TEA1731LTS GreenChip SMPS controller

The TEA1731LTS is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. The TEA1731LTS 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 TEA1731LTS IC.

Features

 SMPS controller IC enabling low-cost applications
 Large input voltage range (12 V to 30 V)
 Integrated OverVoltage Protection (OVP) on VCC
 Very low supply current during start-up and restart (10 A typical)
 Low supply current during normal operation (0.58 mA typical without load)
 Internal overpower time-out
 Overpower or high/low line compensation (NXP patent: 81421271EP01)
 Fixed switching frequency with frequency jitter to reduce EMI
 Frequency reduction at medium power operation to maintain high efficiency
 Frequency reduction with fixed minimum peak current to maintain high .
