R2A20112A
R2A20112A - Brand New RENESAS PFC (Power Factor Correction)
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The R2A20112A controls a boost converter to provide an active power factor
correction.
The R2A20112A adopts critical conduction mode for power factor correction and
realizes high efficiency and a low switching noise by zero current switching.
Interleaving function improves ripple current on input or output capacitor by
180 degrees phase shift.
Soft-star, the feedback loop short detection, two mode over-voltage-
protection, over-current-protection, Over current ON/OFF timer protection for
boost Diode short and slave ZCD open detection are built in the R2A20112A, and
can constitute a power supply system of high reliability with few external
parts.
