~ All models are tested and specified with external 22μF tantalum input and output capacitors.
These capacitors are necessary to accommodate our test equipment and may not be required
to achieve specified performance in your applications. All models are stable and regulate within
spec under no-load conditions.
 Input Ripple Current is tested and specified over a 5-20MHz bandwidth. Input filtering is
CIN = 200μF, CBUS = 1000μF, LBUS = 1μH.
€ Current limit inception is given at either cold start-up or after warm-up.

‚ 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.
ƒ Short circuit shutdown begins when the output voltage degrades approximately 2% from the
selected setting.

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 (specifically pin 6).
I/O Filtering and Noise Reduction
All models in the LSN D12 Series are tested and specified with external 22μF
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,
