1 ISEN A Current sense input pin. Voltage generated across an external sense resistor is fed into this pin. 2 UVLO A Under voltage lockout pin. A resistor divider from VIN to ground is connected to the UVLO pin. The ratio of these resistances determine the input voltage which allows switching and the hysteresis to disable switching. 3 COMP A Compensation pin. A resistor and capacitor combination connected to this pin provides compensation for the control loop. 4 FB A Feedback pin. Inverting input of the error amplifier. 5 AGND G Analog ground pin. Internal bias circuitry reference. Should be connected to PGND at a single point. 6 FA/SYNC/SD I/A Frequency adjust, synchronization, and shutdown pin. A resistor connected from this pin to ground sets the oscillator frequency. An external clock signal at this pin will synchronize the controller to the frequency of the clock. A high level on this pin for ≥ 30 µs will turn the device off and the device will then draw 5 µA from the supply typically. 7 PGND G Power ground pin. External power circuitry reference. Should be connected to AGND at a single point. 8 DR O Drive pin of the IC. The gate of the external MOSFET should be connected to this pin. 9 VCC O Driver supply voltage pin. A bypass capacitor must be connected from this pin to PGND. See Driver Supply Capacitor Selection section. Do not bias externally. 10 VIN P Power supply input pin. 4 LM3481, LM3481-Q1 SNVS346F –NOVEMBER 2007–REVISED NOVEMBER 2014 Product Folder Links: LM3481 LM3481-Q1 Submit Documentation Feedback Copyright © 2007–2014, Texas Instruments Incorporated (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur.
