General PWM-ICs
-
Status:Available
FA5511 is a PWM switching power supply control IC that can directly drive power MOSFETs. It uses a high-voltage CMOS (30 V withstand voltage) device to achieve low power consumption. In addition, despite its 8-pin package, it incorporates a wide variety of protective functions and reduces the number of external components, making it ideal for compact, high-performance, and high-efficiency power supplies that achieve power savings.
Features
- Low current consumption by CMOS process with high dielectric strength (30V)
- Standby current of 2A or less (at Vcc = 14V), and operating current of 1.5mA (typ)
- Overvoltage protection function detecting the Vcc voltage
- A drive circuit for connecting a power MOSFET directly
- Output peak current: ±1.5A
- Pulse-by-pulse overcurrent limiting function
- Overload protection function (latch or non-latch mode selectable)
- Output ON-OFF function by external signal
- Latch-mode overvoltage shutdown function
- Undervoltage lockout function (16.5V ON / 9V OFF)
- Reference voltage output (5V)
- Maximum duty cycle 70%
- Package: SOP-8
Applications
- Switching Power Supplies
