产品特点 FEATURES
The SQ24 Series DC-DC converter (part of Bel Power's SemiQ™ Family) is a compact, high-efficiency power conversion solution with key features:
1
Compact size: Only 60% of industry-standard quarter-bricks, compatible with existing quarter-brick pinouts for drop-in replacement
2
Wide input range: 18-36 VDC
3
Multiple output voltages: 1.0V,1.2V,1.5V,1.8V,2.0V,2.5V,3.3V,5.0V,6.0V,8.0V,12.0V
4
Dual mounting options: Through-hole (SQ24T) and surface mount (SQ24S)
5
Flexible output trim: ±10% for 1.0V/1.2V outputs; -20% to +10% for outputs ≥1.5V
6
Remote sense capability: Compensates for voltage drops between converter and load
7
Comprehensive protection: Input undervoltage lockout (UVLO), output overcurrent (OCP), overvoltage (OVP), overtemperature (OTP)
8
High reliability: MTBF of 3.4 million hours (per Telcordia TR-332 Method I Case1)
9
Safety compliance: Meets UL/CSA 60950-1 and IEC60950-1 standards
10
RoHS options: Lead-free or lead-solder-exempt versions available
11
Low profile: Minimizes airflow shadowing for downstream devices
12
100% automated assembly: Ensures consistent quality
13
Fixed-frequency operation: Stable performance
14
No minimum load requirement: Flexible application
15
On-board input LC-filter: Reduces input ripple
16
Extremely low output/input ripple: Enhances system stability
17
Start-up into pre-biased output: Suitable for systems with existing load voltage
18
Positive/negative logic ON/OFF control: Versatile integration
19
UL94 V-0 flammability rating: Safe operation
使用场景 APPLICATIONS
The SQ24 Series DC-DC converter is suitable for various applications requiring efficient, compact, and reliable power conversion:
1
Telecom and networking: Powering routers, switches, base stations, and line cards (supports battery-backed systems)
2
Data centers: Providing low-voltage power to servers, storage devices, and dense networking gear
3
Industrial control: Powering PLCs, sensors, actuators, and embedded controllers (wide temperature range handles harsh environments)
4
Medical equipment: Compliance with safety standards fits non-invasive diagnostic tools and lab devices
5
Embedded systems: Powering microprocessors, FPGAs, and low-voltage components (trim and remote sense enable precise regulation)
6
Commercial vehicles: For 24V input systems like fleet management devices and in-vehicle electronics
7
Test and measurement: Stable output and low ripple ensure accurate readings
8
Consumer electronics: Space-saving design fits portable and stationary devices
注意事项 PRECAUTIONS
To ensure optimal performance and safety:
1
Remote sense pins: Connect SENSE(-) (pin5) to Vout(-) (pin4) and SENSE(+) (pin7) to Vout(+) (pin8) if not using remote sense
2
Trim pin: Leave pin6 open if no output voltage adjustment is needed
3
Input stability: Add a 100µF electrolytic capacitor (ESR <1Ω) across the input for stability
4
Output capacitance: Do not exceed max external load capacitance (e.g.,1000µF for12V,15000µF for1.0V)
5
Input voltage: Operate within18-36VDC; avoid exceeding 40VDC absolute max
6
Temperature: Do not exceed -40°C to85°C ambient range
7
Fuse selection: Use recommended external input fuse (e.g.,8A for3.3V,6A for12V)
8
Fault handling: Non-latching protections auto-restart after fault removal
9
Remote sense power: Ensure output power does not exceed max when using remote sense
10
Mounting: Follow correct pin length/clearance for through-hole; use recommended pad sizes for surface mount
11
Thermal management: Maintain adequate airflow to keep FET temperatures ≤120°C
12
ON/OFF control: Positive logic auto-starts when pin is open; negative logic auto-starts when connected to Vin(-)
13
Ripple reduction: Add external capacitors (10µF tantalum +1µF ceramic) to minimize output ripple
