Typical Applications
(Continued) (See applications notes above)
Flashlight Finder
TL/H/7969–10
Note:
LM3909, capacitor, and LED are installed in a white translucent cap on the flashlight’s back end. Only one
contact strip (in addition to the case connection) is needed for flasher power. Drawing current through the bulb
simplifies wiring and causes negligible loss since bulb resistance cold is typically less than 2
X
.
4 Parallel LEDs
TL/H/7969–12
Note:
Nominal flash rate: 1.3 Hz. Average I
DRAIN
e
2 mA.
High Efficiency Parallel Circuit
TL/H/7969–13
Note:
Nominal flash rate: 1.5 Hz. Average I
