AN8026
AN8026 is Self-excited RCC pseudo-resonance type AC-DC switching power supply controller manufactured by Panasonic.
Overview
The AN8026 is an IC developed for controlling the self-excited switching power supply employing the RCC pseudo-resonance type control method. It is pact, equipped only with the necessary minimum functions. The maximum on-period and the minimum off-period can be set separately by using the external capacitor and resistor respectively. It is suitable for the power supply of AV equipment.
