■ Description
The FA7630CP(E) is dual channel PWM-type switching power supply control IC.
This IC can drive Pch-MOSFET directly and is optimum for large power DC-DC converter.
This IC has all the necessary protection functions for a power MOSFET. It is optimum for a portable equipment power supply which uses low-voltage input to output comparably large power.
■ Features
• Dual channel PWM-type switching power supply control
• ±2.6% (VREF) and ±3% (VB) reference voltage
• Low voltage operation (Vcc: 5 to 20V)
• Drive circuit for connecting a Pch-MOSFET
• Overload cutoff circuit with timer latch circuit
• Soft start circuit
• Undervoltage lockout function (UVLO)
• Pulse-by-pulse overcurrent limiting function
• Output ON/OFF control function for each channel
• Master-slave synchronized operation without external components
• Maximum operating frequency is 500kHz
