Performance/Functional Specications Table is not implied.
Absolute Maximum Ratings
Return Current Paths
The LSN D12 SIP’s are non-isolated DC/DC converters. Their two Common
pins (pins 5 and 6) are connected to each other internally (see Figure 1). To
the extent possible (with the intent of minimizing ground loops), input return
current should be directed through pin 6 (also referred to as –Input or
Input Return), and output return current should be directed through pin 5
(also referred to as –Output or Output Return). Any on/off control signals
applied to pin 11 (On/Off Control) should be referenced to Common
(specically pin 6).
I/O Filtering and Noise Reduction
All models in the LSN D12 Series are tested and specied with external
22F tantalum input and output capacitors. These capacitors are necessary
to accommodate our test equipment and may not be required to achieve?
desired performance in your application. The LSN D12's are designed with
high-quality, high-performance internal I/O caps, and will operate within spec
in most applications with no additional external components.

All models are tested and specied with external 22F tantalum input and output capacitors.
These capacitors are necessary to accommodate our test equipment and may not be required
to achieve specied performance in your applications. All models are stable and regulate within
spec under no-load conditions.
Input Ripple Current is tested and specied over a 5-20MHz bandwidth. Input ltering is
CIN = 200F, CBUS = 1000F, LBUS = 1H.
Current limit inception is given at either cold start-up or after warm-up.
Mean Time Before Failure is calculated using the Telecordia (Bellcore) SR-332 Method 1,
Case 3, ground xed conditions, TCASE = +25°C, full load, natural convection, +67°C max. PC
board temp.
The On/Off Control (pin 11) may be driven with open-collector logic or by applying appropriate
external voltages which are referenced to Common, pins 5 and 6.
Short circuit shutdown begins when the output voltage degrades approximately 2% from the
selected setting.
