NTE7159
Integrated Circuit
Switch Mode Power Supply Controller
Description:
The NTE7159 is a monolithic integrated circuit in a 16–Lead DIP type package designed for use as
the primary part of an off–line switching mode power supply. All functions required for SMPS control
under normal operating, transient or abnormal conditions are provided.
The capability of working according to the “master–slave” concept, or according to the “primary regulation”
mode makes the NTE7159 very flexible and easy to use. This is particularly true for TV receivers where
the IC provides an attractive and low cost solution (no need of stand–by auxiliary power supply).
Features:
D Positive and Negative Current Up To 1.2A and –2A
D Low Start–Up Current
D Direct Drive of the Power Transistor
D Two Levels Transistor Current Limitation
D Double Pulse Suppression
D Soft–Starting
D Under and Overvoltage Lock–Out
D Automatic Stand–By Mode Recognition
D Large Power Range Capability in Stand–By (Burst Mode)
D Internal PWM Signal Generator
