Подскажите, пожалуйста, чем можно эту микруху заменить, а то ее уже не производят, не знаю где достать.. Вот ее описание:
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 components, 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.
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 components
