Panasonic AN8026 Data Manual
Summary
The AN8026 is a self-excited RCC pseudo-resonance type AC-DC switching power supply control IC. Operating from 8.6V to 34V, it features totem pole output for direct MOSFET driving, pulse-by-pulse overcurrent protection, undervoltage lockout, overvoltage protection, and VF control. The 9-pin SIP package offers design flexibility with separately configurable maximum on-period and minimum off-period via external components. Pre-start current is only 80µA typical. Target users are power supply designers for televisions, facsimiles, printers, scanners, and video equipment requiring compact, efficient AC/DC conversion with comprehensive protection features.

AN8026 Self-excited RCC pseudo-resonance type AC-DC switching power supply control IC
Unit: mm
Overview 6.0±0.3 The AN8026 is an IC developed for controlling the self-excited switching power supply employing the RCC pseudo-resonance type control method. It is compact, equipped only with the necessary mini- mum functions. The maximum on-period and the minimum off-pe- FF riod can be set separately by using the external capacitor and resistor respectively. It is suitable for the power supply of AV equipment.
