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 frequency 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 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 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 derating - 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.

Note 1: Maintain a minimum of 0.4V headroom between input and output voltage to meet performance specifications. Unit will perform as the model with the output voltage that it is trimmed to. Note 2: Tantalum or similar with additional ceramic as needed to reduce ripple current in external input capacitors. See Figure 26. When using more than 1000µF of output capacitance, input filter inductor should be reduced to
