Please provide Pin-out information (pin name and function) for LM2917M (i.e. the 14-pin version)
For LM2917 14-Pin packages only
|
1 |
Input Signal (+), the non-inverting input of the input signal voltage comparator |
|
2 |
Charge Pump Timing, a timing capacitor is charged and discharged at a duty cycle and rate determined by the input signal with the average current value determined by the timing capacitor value |
|
3 |
Charge Pump Output, the average amount of current pumped into, or out of, the timing capacitor is mirrored to the charge pump output load resistor which converts the current into a DC voltage which is integrated (filtered) by a parallel capacitor. |
|
4 |
Op Amp Input (+), the op-amp is used to scale the Charge Pump Output voltage |
|
5 |
Output Transistor Emitter (Current Source), driven by the op-amp output and used to source high current levels to an external load |
|
6 |
No internal connection |
|
7 |
No internal connection |
|
8 |
Output Transistor Collector (Current Sink), driven by the op-amp output and used to sink high current levels from an external load |
|
9 |
V+, Input Supply, internal zener voltage clamp requires external series current limiting resistor |
|
10 |
Op Amp Input (-), the op-amp is used to scale the Charge Pump Output voltage |
|
11 |
Input Signal (-), the inverting input of the input signal voltage comparator |
|
12 |
Ground |
|
13 |
No internal connection |
|
14 |
No internal connection |
