TEA1733LT Overview
Description
The TEA1733LT/N1 is a low cost Switched Mode Power Supply (SMPS) controller ICs intended for flyback topologies. They operate in fixed frequency mode.
Key Features
- SMPS controller IC enabling low-cost applications
- Large input voltage range (12 V to 30 V)
- Very low supply current during start-up and restart (typically 10 A)
- Low supply current during normal operation (typically 0.5 mA 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 with fixed minimum peak current to maintain high-efficiency at low output power levels
- Slope compensation for CCM operation
