SERIES LR
DC-DC CONVERTERS
Wide Input Range/up to 3.33:1
Isolated Regulated up to 5 Watt
DC-DC Converters
Fully Regulated
All Units Shielded
This series of high efficiency, wide input range, encapsulated regulators come in 90 different
models. These units feature a 500 VOLT DC input to output isolation in both single and dual output
models. The LR Series will operate over a temperature range of -25 C to +70 C with no heat sink
or electrical derating. These units are excellent for applications where input voltage varies
dramatically, yet a high efficiency and output voltage regulation must be maintained.
TYPICAL CHARACTERISTICS:
Test conditions: 25 C ambient.
Operating temperature: -25 C to +70 C ambient.
Output voltage tolerance: ±1% at typical input voltage
Output voltage temperature coefficient: 0.02%/C
Storage temperature: -55 C to +125 C
Short circuit protection: Temporary
Operating frequency: 40 KHz, typ.
OPTIONS AVAILABLE
Per Mil. Std. 883
Expanded operating temp. (-55 C to +85 C)
Stabilization Bake (125 C ambient)
Temperature Cycle (-55 C to +125 C)
Hi Temp, full power burn in (100% power, 125 C case temp)
FEATURES
Voltage regulation over input range of
Encapsulated semiconductors, conservatively rated for maximum reliability.
Load regulation (see table for typical variation at different loads)
Line regulation = Typical values
5-15V DC = ±1.5%
8-24V DC = ±1.5%
18-36V DC = ±1.0%
36-60V DC = ±1.0%
18-60V DC = ±1.5%
High efficiency - up to 80%
Will operate over a temperature range of -25 C to +70 C with no heat sink or electrical derating
6 sided shielding
Isolation - 100 megohms at 500 volts DC
External output trimming pin standard, +5%
Single and dual isolated outputs
Each unit is supplied with an external control pin. This "C" pin, when connected to the negative (-) input,
will disable the unit, allowing for remote shutdown.
