R_LEB
Program the leading edge blanking from 50ns to 300ns.
10
7
CS_COMP
Set a low current sharing loop bandwidth with a capacitor.
11
8
CSS
Program the rise time and the clamping voltage with a capacitor and a resistor, respectively.
12
9
EANI
Non-inverting input of Error Amp. It is clamped by the voltage at the CSS pin (Vclamp).
13
10
EAI
Inverting input of Error Amp. It receives the feedback voltage.
14
11
EAO
Output of Error Amp. It is clamped by the voltage at the CSS pin (Vclamp).
15
12
SHARE
This pin is the SHARE BUS connecting with other unit(s) for current share operation.
16
13
LATSD
The IC is latched off with a voltage greater than 3V at this pin and is reset by recycling VDD.
17
14
DCOK
Power Good indication with a ±5% window.
18
15
ON/OFF
This is an Enable pin that controls the states of all drive signals and the soft-start.
19, 20
16, 17
SYNC2, SYNC1
These are the gate control signals for the output synchronous rectifiers.
21, 22
18, 19
LOWER2, LOWER1
Both lower drivers are PWM-controlled on the trailing edge.
23, 24
20, 21
UPPER2, UPPER1
Both upper drivers are driven at a fixed 50% duty cycle.
25
22
PGND
Power Ground. High current return paths for both the upper and the lower drivers.
26, 27
23, 24
VDDP2, VDDP1
Power is delivered to both the upper and the lower drivers through these pins.
28
25
VDD
Power is delivered to all control circuits including SYNC1 & SYNC2 via this pin.
