Pin Name
Pin Function
1
VIN
Controller supply voltage. Also the (+) input to the current sense amp.
2
COMP
Compensation (Output): Internal error amplifier output. Connect to a
capacitor or series RC network to compensate the regulator
s control loop.
3
FB
Feedback Input: The circuit regulates this pin to 1.245V.
4
CS
The (
) input to the current limit comparator. A built in offset of 110mV
between VIN and CSL in conjunction with the current sense resistor sets the
current limit threshold level. This is also the (
) input to the current amplifier.
5
VDD
3V internal linear-regulator output. VDD is also the supply voltage bus for the
chip. Bypass to GND with 1
μ
F.
6
GND
Ground.
7
OUTN
High current drive for the synchronous N-channel MOSFET. Voltage swing
is from ground to VIN. On-resistance is typically 6
at 5V
