Pin Functions
| PIN | TYPE(1) | DESCRIPTION | ||
|---|---|---|---|---|
| NO. | NAME | |||
| A1 | EN | I | EN pin. The device is in shutdown mode when voltage to this pin is < 0.4 V and enabled when > 1.2 V. Do not leave this pin floating |
|
| A2 | VIN | P | Power supply input. Connect to the input filter capacitor. (See Typical Application Circuit.) | |
| B1 | MODE | I | MODE pin: Mode = 1, forced PWM; mode = 0, ECO Do not leave this pin floating. |
|
| B2 | SW | A | Switching node connection to the internal PFET switch and NFET synchronous rectifier. | |
| C1 | FB | A | Feedback analog input. Connect directly to the output filter capacitor. (See Typical Application Circuit.) |
|
| C2 | GND | G | Ground pin. | |
(1) A: Analog Pin, D: Digital Pin, G: Ground Pin, P: Power Pin, I: Input Pin, I/O; Input/Output, O: Output Pin
