PIN 17: PHASE - Over current detection pin. Connect
the PHASE pin to source of the
external MOSFET. This pin detects
the voltage drop across the MOSFET
RDS(ON) for over-current protection.
PIN 18: UGATE- External MOSFET gate drive pin.
Connect UGATE to gate of the
external MOSFET.
PIN 19: BOOT - External MOSFET driver power
supply pin. To convert 5V main power
to VCORE power by driving N-channel
MOSFET, supply voltage of no higher
than 12V is recommended since the
negative power terminal of the
internal driver is internally tied to
GND.
PIN 20: PGND - Driver power GND pin. PGND should
be connected to a low impedance
ground plane in close to lower N-
MOSFET source.
PIN 21: LGATE - Lower N-MOSFET gate driver pin.
PIN 22: VCC
- The chip power supply pin. It also
serves as power supply for LGATE
driver. Recommended supply voltage
is 12V.
PIN 23: OVP
-Over voltage indicator pin. This pin
also provides a driver source current
to turn on an external SCR in the
event of an over voltage condition.
PIN 24: RT
- Frequency
adjustment
pin.
Connecting a resistor (RT) from this
pin to GND, increase the frequency
by the following equation.
