1
N/C
No Connection
2
ENABLE
TTL compatible input with internal 4uA pullup. Floating or Venable> 1.5V will
enable the part, Venable < 0.65V disables part.

ISP
Current Sense Positive Input: Rail to Rail Input for Over-Current Detection,
43mV threshold with 10
μ
s (typ) response time.
4
ISN
Current Sense Negative Input: Rail to Rail input for Over-Current Detection.
5
V
FB
Feedback Voltage Pin: Inverting input of the error amplifier and serves as the
output voltage feedback point for the buck converter. The output voltage is
sensed and can be adjusted through an external resistor divider.
6
COMP
Error Amplifier Compensation Pin: A lead lag network is typically connected
to this pin to compensate the feedback loop. This pin is clamped by the SS
voltage and is limited to 2.8V maximum.
7
SS
Soft Start Programming Pin: This pin sources 50

1
μ
F capacitor on this pin is typically enough capacitance to soft start a power
supply. In addition, hiccup mode timing is controlled by this pin through the
5
μ
A discharge current. The SS voltage is clamped to 2.7V maximum.
8
R
OSC
Frequency Programming Pin: A resistor to ground is used to program
frequency. Typical values - 18,700

PGND
Power Ground Pin: Used for Power Stage. Connect Directly to GND at I.C.
pins for optimal performance.
13
GND
Ground Pin: Main ground pin for I.C.
14
SWN
Switch Node Reference: High side MOSFET driver reference. Can also be
tied to GND for low voltage applications.
15
GH
HIgh Side MOSFET Driver: Can be NFET or PFET depending on Program
Mode. 1nF/20ns typical drive capability. Maximum voltage rating is
referenced to SWN.
