TEA1731LTS
GreenChip SMPS control IC

Product data sheet
1. General description
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 OverPower Protection (OPP). The controller accepts an
overpower situation for a limited amount of time.
One pin is reserved for protection purposes. OverTemperature Protection (OTP) can be
implemented with a minimal number of external components.
At low-power levels, the primary peak current is set to 25 % of the maximum peak current.
The switching frequency is reduced to limit the 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 TEA1731LTS makes the design of low cost, highly efficient and reliable supplies for
power requirements up to 75 W easier by requiring a minimum number of external
components.
2. Features and benefits
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 efficiency at
low output power levels
Frequency increase at peak power operation
Slope compensation for CCM operation
Adjustable soft start
Low and adjustable OverCurrent Protection (OCP) trip level
