| Description | The TEA2260/61 is a monolithic integrated circuit for the use in primary part of an off-line switching mode power supply. All functions required for SMPS control under normal operating, transient or a... |
| Features |
the following functions : - Power supply start-up (with soft-start) - PWM generator - Direct power transistor drive (+1.2A, -2.0A) - Safety functions : pulse by pulse current limitation, output power limitation, over and under voltage lock-out. S.M.P.S. OPERATING DESCRIPTION Starting Mode - Stand By Mode Power for circuit supply is taken from the mains through a high value resistor before starting. As long as VCC of the TEA2260/61 is below VCC start, the quiescent current is very low (typically 0.7mA) and the electrolytic capacitor across VCC is linearly charged. When VCC reaches VCC start (ty... |
