Overview

DESCRIPTION

· The TEA1733CP is a low-cost SMPS controller IC designed for flyback topologies, operating in fixed frequency mode with frequency jitter to reduce EMI.
· It integrates slope compensation for CCM operation and includes OverPower Protection (OPP) for limited overpower operation.
· Protections like UVP, OVP, and OTP can be implemented with minimal external components.
· Optimized for high efficiency across the load range, it reduces switching frequency at low power levels and supports power requirements up to 75 W.



FEATURES

· Enables low-cost SMPS applications with a wide input voltage range (12 V to 30 V).
· Low supply current during start-up (10 µA) and normal operation (0.5 mA without load).
· Features overpower compensation, adjustable overpower time-out, and restart timer.
· Fixed switching frequency with jitter for EMI reduction and frequency reduction at low power for efficiency.
· Includes slope compensation for CCM and adjustable OCP trip level.



APPLICATIONS

· Suitable for designing low-cost, efficient, and reliable power supplies up to 75 W.
· Ideal for applications requiring flyback topology with integrated protection features.
