FUNCTION
Compensation Input. Connect a 0.1μF ceramic capacitor from COMP to GND for regulator stability.
Enable Input 1. EN1 and EN2 set the operating mode (see Table 1).
Enable Input 2. EN1 and EN2 set the operating mode (see Table 1).
Movie Current Program Input. Connect a resistor from MOV to GND to set the LED current in movie mode.
R MOV must be greater than 2k ? .
Flash Current Program Input. Connect a resistor from FLSH to GND to set the LED current in flash mode.
R FLSH must be greater than 2k ? .
Analog Ground. Connect GND to the exposed paddle directly under the IC.
LED Current Regulator Ground. Connect LGND to the ground plane on the PC board.
LED Current Regulator. Connect LED to the cathode of the external LED. LED is high impedance during shutdown.
Power Ground. Connect PGND to the input capacitor ground. Also, connect PGND to the PC board ground plane.
Inductor Connection. Connect LX to the switched side of the inductor. LX is internally connected to the
drains of the internal MOSFETs. Both MOSFETs are off during shutdown.
Regulator Output. Connect OUT to the anode of the external LED. Bypass OUT to PGND with a 10μF or
larger ceramic capacitor. During shutdown, OUT is one body-diode drop below the input voltage.
Output Sense and IC Supply Input. Connect OUTS to OUT at the output bypass capacitor. The IC’s operating
power is supplied from OUTS.
Exposed Paddle. Connect the exposed paddle to GND directly under the IC and to a large PC board
ground plane for increased thermal performance.
