Introduction
TEA1832LTS is a low-cost SMPS controller IC designed for flyback topology. It operates in peak current and frequency control mode, employs frequency jitter to reduce EMI, and integrates slope compensation for CCM operation. The IC features over-power protection (OPP), allowing the controller to withstand up to 200% over-power conditions for a limited duration. Mains brownin/brownout protection, output OVP, and OTP can be implemented with a minimum number of external components. At low power levels, the primary peak current is set to 22% 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 enables high efficiency across the entire load range. By using a minimum number of external components, the TEA1832LTS simplifies the design of low-cost, efficient, and reliable power supplies, making it particularly suitable for medium-power applications.
Features
- SMPS controller IC for low-cost applications
- Wide input voltage range (10.5 V to 36 V)
- Integrated OVP on VCC pin
- Accurate OVP via ISENSE pin
- Dedicated burst mode allowing low VCC capacitor values
- Ultra-low supply current during startup and restart (typical 11 μA)
- Low supply current during normal operation (typical 0.58 mA at no load)
- Internal over-power timeout
- Over-power protection with high/low line compensation
- Fixed switching frequency with frequency dithering for reduced EMI
- Frequency reduction at fixed minimum peak current for high efficiency at low output power levels
- Peak power operation up to 200% via increased frequency and peak current
- Slope compensation for CCM operation
- Integrated soft-start
- Gate drive capability: source 300 mA, sink 750 mA
- Maximum duty cycle set to 90%
- Mains under-voltage protection (brownin/brownout)
- Output short-circuit protection (OSCP) to prevent transformer saturation
- External OTP
- IC over-temperature protection
- Maximum duty cycle protection and brownin/brownout protection trigger restart; all other protections are latched
Applications
- All applications requiring efficient and cost-effective power solutions
- Mid-power applications
