NQ04025VMA15ORS 3.0-5.5V In, 2.5V Out @15A by SynQor
15A Non-Isolated DC/DC Converter in SIP Configuration
DESCRIPTION: 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.
Typical applications include telecom/datacom,
industrial, medical, transportation, data
processing/storage and test equipment.
PERATIONAL FEATURES:
- Ultra-high efficiency, up to 94% full load, 95% half
- Delivers 15 amps of output current with minimal derating - no heatsink required
- Input voltage range: 3.0 - 5.5V
- 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
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
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 here in vertical mounting
CONTROL FEATURES:
- On/Off control
- Output voltage trim (industry standard) permits
custom voltages and voltage margining
- Remote sense (standard option)
These converters are new and unused -- taken from manufacturer's original packaging.
