Pin Descriptions Pin Number Pin Name Description 1EN Active-High Enable Input. A logic low on this pin shuts down the device and reduces the supply current to 0.1µA. Note: Connect to VCC for normal operation. 2VCC +2.7V to +5.5V Supply Voltage. Bypass this pin to GND with a ≥1µF capacitor. 3SWVIN Shutdown Disconnect Switch In 4POK Power-OK. 0 = VOUT < 90% of VOUTNOM. 1 = VOUT > 90% of VOUTNOM. 5LX Inductor. The drain of the internal N-channel MOSFET. Note: This pin is high impedance in shutdown. 6SWOUT Shutdown Disconnect Switch Out. Disconnects the input from the output during shutdown. 7GND Ground. This pin and pin 9 must be connected to GND to ensure normal operation. 8FB Feedback Pin. Feedback input to the gm error amplifier. Connect a resistor divider tap to this pin. The output voltage can be adjusted from VIN to 50V by: VOUT = 1.25V[1 + (R1/R2)] 9GND Ground. This pin and pin 7 must be connected to GND to ensure normal operation. 5LX 3 SWVIN 2 VCC 1 EN 8FB AS1340 4 POK 7GND 6 SWOUT 9 GND |
