FA7611CP(E) is a bipolar IC produced by Panasonic that contains the basic circuit necessary for PWM-type switching power supply control. This chip has low voltage operation (VCC = 3.6 to 22V), pre-drivers (CH1 is open-collector output or bipolar output, CH2 is open-collector output), power supply lockout function, soft-start function, and one capacitor shared for short circuit protection and soft start to minimize the number of external discrete components.
This manual describes the FA7611CP(E) bipolar integrated circuit designed for PWM‑type switching power supply control. It lists key features such as low‑voltage operation, latch‑mode short‑circuit protection, soft‑start, and undervoltage lock‑out, and includes a block diagram and pin‑out table.
The document also provides absolute maximum ratings, recommended operating conditions, electrical characteristics, characteristic curves, and example application circuits for flyback‑transformer and buck‑converter topologies.
