Non-Isolated
SIP Converter
3.0 - 5.5Vin 16A
16Amp, wide ouput range, Non-Isolated DC/DC Converter
The NiQor
™
SIP DC/DC converter is a non-isolated
buck regulator, which employs a fixed switching fre-
quency and synchronous rectification to achieve
extremely high conversion efficiency. 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 cre-
ate the low voltage outputs required by the design.
The wide trim module can be programmed to a vari-
ety of output voltages through the use of a single
resistor.
Non-Isolated
NiQor vertical mount SIP module
Operational Features
• Ultra-high efficiency, up to 94% full load, 95% half
• Delivers 16 amps of output current with minimal der-
ating - no heatsink required
• Input voltage range: 3.0 - 5.5V
• Programmable output voltages from 0.85 - 3.6V
• Fixed frequency switching provides predictable EMI
performance
• 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
• Remote sense (standard option)
• Fixed output voltage 15A modules available
(0.9V - 3.3V)
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 (>4.4V)
• Thermal shutdown
* Final datasheet pending ECO review and signature.
Product # NQ04T33VMA16
Phone 1-888-567-9596
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
