onsemi PMIC - PMIC - AC DC Converters, Offline Switchers - NCP1360BABCYSNT1G NCP1360BABCYSNT1G

The NCP1360BABCYSNT1G is a low power offline constant current and constant voltage primary side PWM current-mode controller designed for universal mains flyback applications, targeting output power levels from a few watts up to 20 W. This device eliminates the need for secondary feedback circuitry, such as opto-couplers and TL431 references, while maintaining excellent line and load regulation. It operates in valley-lockout quasi-resonant peak current mode control, which enhances efficiency at nominal loads. The controller features a startup current source rated at 560 V and offers options for maximum switching frequencies of 80 kHz or 110 kHz. Key features include ±5% voltage regulation, ±10% current regulation, cycle-by-cycle peak current limit, built-in soft-start, and over/under output voltage protection. Additionally, it supports cable drop compensation with multiple options. The NCP1360BABCYSNT1G is packaged in a TSOP-6 form factor and is suitable for applications such as low power AC-DC adapters and USB chargers for various devices. Its low no-load performance, less than 10 mW for the NCP1365 version and less than 30 mW for the NCP1360 version, makes it an efficient choice for energy-sensitive designs.
