performance miniature DC-DC converters
having regulated outputs over the wide
temperature range of –40°C to 85°C. The
input voltage range is 2:1 with the output
power at 2 watts and the input to output
isolation is 1kVDC. Continuous short circuit
protection, external control and extremely
small SIP packaging provide state of the art
functionality. The use of ceramic capacitors
and a ceramic substrate, with a tough chip
and wire bonded MOSFET power transistor
die and SMD construction, provide genuine
high reliability. Nominal input voltages of
5,12,24 and 48V with output voltages of
5,9,12 and 15V are available as standard
with custom parts on request. The plastic case
is rated to UL 94V-0 with encapsulant to UL
94V-1. Connection pins are phosphor bronze
with a 60/40 tin lead solder dipped finish.

Measured at full load with external input/output capacitors, refer to recommended test circuit.
A lower load condition is entirely safe but higher levels of output ripple will be experienced.
Calculated using MIL-HDBK-217F with nominal input voltage at full load.

Refer to recommended test circuit for external input/output capacitors.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.

CTRL (PIN 3)
ISOLATION CHARACTERISTICS
Provides an on/off function. The converter
is on when CTRL is not connected or high
impedance (Z). The CTRL pin will turn the
converter off as indicated in general
characteristics.

Additional capacitance, up to 100uF can be
added from CS to pin 7. A low ESR
capacitor if fitted will precede the output filter
inductor and will improve ripple and noise.
Control voltage applied via 1k0 resistor,
output voltage must reduce to 0V
