FA7617CP Datasheet | Fuji Electric

Description The FA7610CP(N), 7612CP(N) and 7617CP(N) are bipolar ICs containing basic circuits necessary for PWM-type switching power supply control. To minimize the number of external discrete ponents, the FA7610CP(N) is provided for a flyback or step-up powersupply circuit, the FA7612CP(N) for a step-down power-supply circuit and FA7617CP(N) for a flyback power supply circuit. s Dimensions, mm SOP-8 8 5 s Features FA7610CP(N) - For flyback transformer-type or step-up power-supply circuit (maximum output duty = 64% typical) - Totem-pole predriver - PWM-type switching power supply control - Low-voltage operation (VCC = 3.6 to 22V) - Latch-mode short-circuit protection function (no malfunction by noise) - Soft-start function - Undervoltage lockout function - One capacitor shared for short circuit protection and for softstart to minimize the number of external discrete ponents FA7612CP(N) - For step-down power-supply circuit (maximum output duty = up to 100%) - Open collector output - PWM-type switching power supply control - Low-voltage operation (VCC = 3.6 to 22V) - Latch-mode short-circuit protection function (no malfunction by noise) - Soft-start function - Undervoltage lockout function - One capacitor shared for short circuit protection and for softstart to minimize the number of external discrete ponents FA7617CP(N) - For flyback transformer-type power-supply circuit (maximum output duty = 67% typical) - Open collector output - PWM-type switching power supply control - Low-voltage operation (VCC = 3.6 to 22V) - Latch-mode short-circuit protection function (no malfunction by noise) - Soft-start function - Undervoltage lockout function - One capacitor shared for short circuit protection and for softstart to minimize the number of external discrete ponents 1 4.9 +0.1 - 0.05 6.0±0.2 0.4±0.1 1.27±0.2 DIP-8 8 5 9.3...
