This document introduces the characteristics of the L6561 product, including micro power start-up current, very low operating current, internal start-up timer, current sense filter on chip, disable function, 1% precision internal reference voltage, transition mode operation, symmetric output current.
The L6561 is an improved Power Factor Corrector (PFC) IC designed for wide input voltage range applications (85V to 265V). It features transition mode operation to ensure excellent Total Harmonic Distortion (THD) and includes a disable function on the ZCD pin for lower standby current consumption. The device is compatible with the standard L6560 version but offers superior performance with a reduced start-up current and internal start-up timer.
| Operating Input Voltage Range | 85V to 265V |
|---|---|
| Operating Supply Voltage | 11 to 18 V |
| Turn-on Threshold | 11 to 13 V |
| Turn-off Threshold | 8.7 to 10.3 V |
| Quiescent Current | 2.6 to 4 mA |
| Output Totem Pole Peak Current | +700 mA |
| Internal Reference Voltage Precision | 1% |
| Junction Temperature Operating Range | -40 to 150 °C |
The typical start-up current is 50 µA.
Grounding the ZCD pin disables the device, reducing supply current consumption to 1.4 mA typical.
The device is available in DIP-8 and SO-8 packages.
