Technical Specification
Non-Isolated
SMT Converter
9.6 - 14.4Vin 16A
16A Non-Isolated, SMT DC/DC Converter with wide trim
The NiQor^™ SMT DC/DC converter is a non-isolat-
ed buck regulator, which employs synchronous rec-
tification 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. The wide trim module can
be programmed to a variety of output voltages
through the use of a single external resistor.

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
• Programmable output voltages from 0.85 - 5.0V
• On-board input and output filter capacitor
• No minimum load requirement means no preload
resistors required
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
