Description
Internal LDO power supply
Top MOSFET driver input supply, place a ceramic capacitor between LX and BST.
Output voltage power good indication. The power good pin is an open drain indication flag. The PGOOD
pin is low impedance if the output voltage is outside the comparator window and is high impedance if the
output voltage is inside the comparator window.
The enable pin is used to enable the part and also set skip mode or forced PWM.
Output of the error amplifier
Output voltage feedback
Output voltage monitor
Analog ground
Frequency selection pin, 0 V = 333k, No connect = 500 kHz, 5 V = 1.0 MHz
Output to the internal power supply for the analog circuitry
Ground reference and high ? current return path for the bottom power MOSFET.
Switch node between the top MOSFET and bottom MOSFET.
High Side MOSFET input voltage connection
Connect to PGND for thermal enhancement. Exposed pad is not electrically connected.
