Pin name
Description
15
FB
Feed back input pin. The minus terminal (-) of the trans conductance amplifier is connected.
The voltage generated when the output voltage was divided by a resistor is input into this pin.
The converter operates so that this pin becomes an internal reference voltage (VREF=0.836V).
Also, this pin is monitored by the comparators UVP and OVP.
When the voltage of this pin becomes less than 87% of the set voltage, the PGOOD pin is low level.
A timer of the UV_DELAY function operates. Also, when the voltage of this pin becomes more than 117% of the set voltage,
the IC latches off.
16
COMP
The pin to connect a capacitor and a resistor for phase compensation.
The output of an internal transformer conductance amplifier is connected.
Connect an external phase compensation circuit between this pin and SGND.
17
SGND
The system ground of the IC. The reference voltage is generated based on this pin.
This pin is connected to the power supply system ground.
18
VDD
Power supply pin for the gate drive of an external lower-side MOS-FET.
This pin is connected to the VLIN5 pin through a filter.
19
LDRV
The gate drive pin of an external lower-side MOS-FET.
This pin has the signal input part for prevention of short-through of both the upper and lower MOS-FETs.
When the voltage of this pin becomes less than 1V, the HDRV pin is turned on.
20
PGND
Power ground pin. This pin becomes the return current path of the LDRV pin.
