The NCP1207A/B series are high-performance current mode controllers designed for quasi-resonant, border-line, or critical conduction mode switching power supplies. Featuring dynamic self-supply, overvoltage and overcurrent protections, and adjustable skip cycle levels, these devices optimize efficiency and reduce EMI noise. They operate in burst mode at light load, ensuring quiet operation and improved power management. With integrated demagnetization detection, latchoff fault protection, soft-start, and high-voltage technology, the NCP1207A/B are ideal for low-cost AC/DC adapters, battery chargers, consumer electronics, and auxiliary power supplies, providing reliable and rugged control in SMPS applications.
