TEA1733P
description
The TEA1733T, TEA1733P, TEA1733LT and TEA1733LP are low cost Switched Mode Power Supply (SMPS) controller ICs intended for flyback topologies. They operate in fixed frequency mode. To reduce Electro Magnetic Interference (EMI), frequency jitter has been implemented. Slope pensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1733(L) includes Over Power Protection (OPP). This enables the controller to operate under overpower situations for a limited amount of time. Two pins, VINSENSE and PROTECT, are reserved for protection purposes. Input Under Voltage Protection (UVP) and Over Voltage Protection (OVP), output OVP and Over Temperature Protection (OTP) can be implemented using a minimal number of external ponents. At low power levels the primary peak current is set to 25 % of the maximum peak current and the switching frequency is reduced to limit switching losses. The bination of fixed frequency operation at high output power and frequency reduction at...
