PIN DESCRIPTION
Pin Number
Pin Type Pin Name
Pin Description
27
OUT
HSDRV_CH3
The HSDRV_CH3 (Channel 3 High-side Driver) pin is the upper
switching node of the channel 3 synchronous buck controller. Attach
to the gate of p-channel MOSFET. A delay exists between the
assertion of HSDRV_CH3 and assertion of LSDRV_CH3 to prevent
excessive current flow during switching.
28
IN
PWREN0
The PWREN0 (Power Enable 0) pin is a programmable input used to
enable (disable) selected supplies. When unused this pin should be
tied to a solid logic level.
29
IN
COMP2_CH3
The COMP2_CH3 (Channel 3 secondary Compensation) pin is the
secondary compensation input of the channel 3 buck controller.
30
IN
COMP1_CH3
The COMP1_CH3 (Channel 3 primary Compensation) pin is the
primary compensation input of the channel 3 buck controller. Each
pin is internally connected to a programmable resistor divider.
31
IN
VM_CH3
The VM_CH3 (Channel 3 Voltage Monitor) pin connects the channel
3 controller output. Internally the VM_CH3 pin connects to an internal
programmable resistor divider.
32
PWR
GND
The GND pin should be connected to the common ground plane
through a short fat wire.
PAD
PWR
GND
The exposed metal pad should be attached to ground.
