Non-Isolated
SIP Converter
9.6 - 14.4Vin 16A
16A Non-Isolated DC/DC Converter in SIP configuration
The NiQor
™
SIP DC/DC converter is a non-isolated
buck regulator, which employs synchronous rectifi-
cation to achieve extremely high conversion effi-
ciency. The NiQor family of converters are used
predominately in DPA systems using a front end
DC/DC high power brick (48Vin to low voltage bus).
The non-isolated NiQor converters are then used at
the point of load to create the low voltage outputs
required by the design. Typical applications include
telecom/datacom, industrial, medical, transportation,
data processing/storage and test equipment.
Non-Isolated
NiQor vertical mount SIP module
Operational Features
• Ultra-high efficiency, up to 95% at full and half load
• Delivers 16 amps of output current with minimal der-
ating - no heatsink required
• Input voltage range: 9.6 - 14.4V
• Fast transient response time
• On-board input and output filter capacitor
• No minimum load requirement means no preload
resistors required
Mechanical Features
• Industry standard SIP pin-out configuration
• Industry standard size: 2.0” x 0.55” x 0.29
(50.8 x
14 x 7.3mm)
• Total weight: 0.30 oz.
(9.4 g)
, lower mass greatly
reduces vibration and shock problems
• Open frame construction maximizes air flow cooling
• Available in both vertical and horizontal mounting
Control Features
• On/Off control
• Output voltage trim (industry standard) permits
custom voltages and voltage margining
• Optional features include remote sense and wide
output voltage trim
(0.85V - 5.0V) - see wide trim
NQ12T50 datasheet
Protection Features
• Input under-voltage lockout disables converter at
low input voltage conditions
• Temperature compensated over-current shutdown
protects converter from excessive load current or
short circuits
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown
Safety Features
• UL 1950 recognized (US & Canada)
• TUV certified to EN60950
• Meets 72/23/EEC and 93/68/EEC directives
which facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flam-
mability requirements
