Pin Function
Controller supply voltage. Also the (+) input to the current sense amp.
Compensation (Output): Internal error amplifier output. Connect to a
capacitor or series RC network to compensate the regulator ’ s control loop.
Feedback Input: The circuit regulates this pin to 1.245V.
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.
3V internal linear-regulator output. VDD is also the supply voltage bus for the
chip. Bypass to GND with 1 μ F.
Ground.
High current drive for the synchronous N-channel MOSFET. Voltage swing
is from ground to VIN. On-resistance is typically 6 ? at 5V IN .
High current drive for the high side P-channel MOSFET. Voltage swing is
from ground to VIN. On-resistance is typically 6 ? at 5V IN .
