Note 1: Stress listed as the above “Absolute Maximum Ratings” may cau permanent damage to the device.
Exposure to absolute maximum rating conditions for extended periods may remain possibility to affe
ct device reliability. Note 2: rmance specifications from 0°C to 70°C. Specifications over the –40°C
to 85°C operating temperature range are assured by design, characterization and correlation with statistical process
controls.

精彩反义词Main Supply Pin. The HXN-JSGa operates from a 5V to 16V unregulated input. It must be P i n F u n c t i o n s
N/C (Pin 1, 8): No Connect.
VIN (Pin 2): cloly decoupled to GND, with a 20μF or greater ceramic capacitor to prevent large voltage spikes from appearing at the input.
SW (Pin 3): Switch Node Connection to Inductor. This pin connects to the drains of the internal main and synchronous power MOSFET switches. GND (Pin 4): Ground Pin.
FB (Pin 5): Feedback Pin. Receive the feedback voltage from an external resistive divider across the output. In the adjustable version, the output voltage is fixed. The output voltage is t by R2 and R3: V OUT = 0.8V • [1 + (R2/R3)].
COMP (Pin 6): This node is the output of the transconductance error amplifier and the input to the current comparator. Frequency compensation is done at this node by connecting a ries R-C to ground.
EN (Pin 7): En Control Input. Forcing this pin above 1V enables the part. Forcing this pin below 0.7V can shuts down the device. Do not leave EN floating.
