7ch switching regulator controller

BD9713KV

Description

BD9713KV is a PWM switching regulator controller IC.
7 channel switching regulator controllers are incorporated
into a VQFP48 package. This IC can drive external
P-channel FET directly. Reference voltage, triangular
wave oscillator, PWM comparator, CMOS type driver,
short-circuit protection circuit, and under voltage lock out
circuit are all incorporated in this IC.

Features

1) 7-channel driver for main switch are incorporated and
P-Ch FET can be driven directly.

2) Built-in short circuit protection (Timer latch type)
when over loaded

3) Built-in under voltage lock out circuit

4) All channels can be OFF or 5, 6, 7 channels
can be set OFF independently.

5) Circuit current is 10 mA or less, when all channels are OFF.

6) Built-in high-precision reference voltage circuit (±1%)
