TEA1833TS
GreenChip SMPS control IC
Rev. 1 — 31 August 2015
Product data sheet
1. General description
The TEA1833TS is a low-cost Switched Mode Power Supply (SMPS) controller IC
intended for flyback topologies. The TEA1833TS 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 TEA1833TS IC features OverPower Protection (OPP). The controller accepts an
overpower situation up to 200 % for a limited amount of time.
Mains undervoltage protection (brownin/brownout), 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 22 % 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 TEA1833TS makes the design of low-cost, highly efficient and reliable supplies
easier by requiring a minimum number of external components. The device is especially
suited for medium power applications.
2. Features and benefits
SMPS controller IC enabling low-cost applications
Large input voltage range (10.5 V to 36 V)
Integrated OverVoltage Protection (OVP) on the VCC pin
Accurate OverVoltage Protection (OVP) via the ISENSE pin
Dedicated burst mode, allowing a low VCC capacitor value
Very low supply current during start-up and restart (11 A typical)
Low supply current during normal operation (0.58 mA typical without load)
Adaptive internal overpower time-out
Overpower protection including high/low line compensation
Fixed switching frequency with frequency jitter to reduce EMI
Frequency reduction with fixed minimum peak current to maintain high efficiency at
low output power levels
Peak power operation up to 200 % by frequency increase and peak current increase
Slope compensation for CCM operation
