TEA1733LP - NXP

TEA1733LP GreenChip III SMPS control IC

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 ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1733(L.

Features

2.1 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 μA) 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 „ Low and adjustable.
