Pt4554c Upd Review

Control boards in air conditioners, rice cookers, or washing machines use the PT4554C to generate 5V logic power for microcontrollers (MCUs) from a 12V or 18V rail.

Operates in QR mode to minimize switching losses and achieve a high efficiency of up to 93% . pt4554c

Calculate the output voltage using the two resistors connected to pin 5 (FB). Formula: Vout = 0.6V (or 0.8V) * (1 + R1/R2) . This will tell you exactly what voltage the PT4554C is supposed to output. Control boards in air conditioners, rice cookers, or

is a high-precision, non-isolated buck LED constant current driver IC designed by Control boards in air conditioners

The use of PT4554C offers several advantages:
