Function
“HS_DRV” is the gate driver of the high ? side MOSFET.
“BST” is the bootstrap pin. A 0.1 m F to 1.0 m F ceramic capacitor should be connected between this pin
and the node that is common to the coil and the two MOSFET. The “BST” voltage feeds the high ? side
driver (“HS_DRV”).
The “RST” pin resets the C_ramp voltage in order to synchronize the post ? regulator free ? wheeling
sequence to the forward converter demagnetization phase.
The capacitor connected to the C_ramp pin enables to adjust the delay in turning on the high ? side
MOSFET (in conjunction with “I_ramp” current).
The “I_ramp” pin receives a current supplied by a regulation means. This current adjusts the delay after
which the high ? side MOSFET is turned on. By this way, it modules the high ? side MOSFET on time in
order to regulate the output voltage.
“V DD ” is the power supply input. A 0.1 m F to 1.0 m F ceramic capacitor should be connected from this pin
to ground for decoupling.
“LS_DRV” is the driver output of the low ? side MOSFET gate.
Ground.
