DESCRIPTION
NAME
NO.
VO
1
Connect to output of converter. This pin is used for On-Time Adjustment.
VFB
2
Converter feedback input. Connect with feedback resistor divider.
VREG5
3
5.5 V power supply output. A capacitor (typical 1
μF) should be connected to GND.
SS
4
Soft-start control. A external capacitor should be connected to GND.
GND
5
Signal ground pin
PG
6
Open drain power good output
EN
7
Enable control input
Ground returns for low-side MOSFET. Also serve as inputs of current comparators. Connect PGND and
PGND1, PGND2
8, 9
GND strongly together near the IC.
Switch node connection between high-side NFET and low-side NFET. Also serve as inputs to current
SW1, SW2
10, 11
comparators.
Supply input for high-side NFET gate driver (boost terminal). Connect capacitor from this pin to
VBST
12
respective SW1, SW2 terminals. An internal PN diode is connected between VREG5 to VBST pin.
VIN
13
Power input and connected to high side NFET drain
VCC
14
Supply input for 5 V internal linear regulator for the control circuitry
Thermal pad of the package. Must be soldered to achieve appropriate dissipation. Should be connected
