Pin Function
Compensation (Output): Internal error amplifier output. Connect to a capacitor or
series RC network to compensate the regulator’s control loop.
Feedback (Input): Regulates FB to 1.245V.
Enable/Undervoltage Lockout (input): A low level on this pin will power down the
device, reducing the quiescent current to under 0.5 μ A. This pin has two separate
thresholds, below 1.5V the output switching is disabled, and below 0.9V the device is
forced into a complete micropower shutdown. The 1.5V threshold functions as an
accurate undervoltage lockout (UVLO) with 100mV hysteresis.
The (+) input to the current limit comparator. A built in offset of 100mV between CS
and GND 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 N-Channel MOSFET. Voltage swing is from ground to VIN.
R ON is typically 3 ? @ 5V IN .
Input voltage to the control IC. This pin also supplies power to the gate drive circuit.
