Output adjustment, control and protection

Trim connection and equation Connect the external Rtrim resistor between Trim pin 6 and GND. Rtrim (kΩ) = 49.1355 / (Vo − 0.895) − 10.7, with Vo in volts.
Trim resistor reference table Vo → Rtrim: 5.5 V → 0 kΩ (short); 5 V → 1.3 kΩ; 3.3 V → 9.8 kΩ; 2.5 V → 20.2 kΩ; 1.8 V → 44.2 kΩ; 1.5 V → 71.3 kΩ; 1.2 V → 150 kΩ; 0.895 V → open (∞). The open-resistor table gives 0.895 V while the specified adjustment range begins at 0.9 V.
Remote ON/OFF Positive logic: power ON with Remote open or 1.6 V < R.C < 5 V; power OFF with Remote shorted to GND or 0 V < R.C < 0.1 V. In the example external transistor circuit, Q1 OFF turns the converter ON and Q1 ON turns it OFF.
Short-circuit protection Continuous short-circuit protection (no damage), with automatic recovery.

Environment and thermal limits

Cooling and working environment Free-air convection; −40 to +82°C with derating; 20–90% RH, non-condensing.
Ambient-temperature derating The 20 LFM airflow curve permits 100% load from −40 to +65°C, then falls to 70% at +70°C, 20% at +80°C and zero at +82°C. Apply the full curve between these points.

EMC emissions Conducted and radiated BS EN/EN55032 Class A with external components. Apply the model-specific external circuits below and verify the complete equipment.

EFT and surge immunity EFT/burst: BS EN/EN61000-4-4, Level 3, 2 kV. Surge: BS EN/EN61000-4-5, Level 4, 2 kV. The specified external protection circuit is required.
Radiated Class A external circuit PDF page 8 uses C1 = 2.2 µF MLCC across the input and L1 = 1.5 µH in series with +Vin. The negative input, module GND and load return share the return node.
EFT and surge external circuit The separate PDF page 8 circuit places TVS 5.0SMLJ22CA-IP and C1 across the input. Its BOM prints C1 as “2200 µH”, although the diagram uses a capacitor symbol.

Surface-mount assembly and storage

Automated placement Open-frame construction is intended for automated assembly. The manufacturer suggests picking and placing over the inductor; optimize nozzle size, tip style, vacuum pressure and placement speed for the assembly process.
Moisture sensitivity MSL level 3. Follow J-STD-033 for moisture-sensitive surface-mount handling, packing, shipping and use.
Dry packing and floor life Use a moisture-barrier bag with desiccant for MSL 3 or higher and keep it sealed until use. After opening, the listed floor life is 168 hours at ≤30°C and 60% RH. Dry-packed shelf life is at most 12 months from the bag-seal date when stored below 40°C and below 90% RH.
Cleanliness before soldering Keep solder pads clean and handle boards carefully to avoid contamination and excess gas generation when flux reacts with oxides or contaminants.
Lead-free reflow process J-STD-020 moisture/reflow classification; recommended forced-air-convection reflow with Sn/Ag/Cu (SAC) solder paste. Soldering outside the recommended profile requires testing to verify performance.
Reflow preheat 150°C minimum to 200°C maximum preheat temperature, with 60–120 seconds between these temperatures.
Reflow peak and dwell Peak 245°C; 20–40 seconds within 5°C of the peak. Maintain temperature above 217°C for 60–150 seconds.
Reflow ramp limits Average ramp-up from maximum preheat to peak: 3°C/s maximum. Ramp-down from peak to liquidus: 6°C/s maximum. Time from 25°C to peak: 8 minutes maximum.

Applications, reliability and packing

Typical applications Telecom, server and storage equipment, industrial control, distributed power architectures, intermediate-bus applications, renewable energy, battery management systems (BMS) and field-programmable gate arrays (FPGA).
Application examples The SPOL-01 diagrams illustrate industrial-PC rails for hard disk, memory, MCU, display, level shifter, USB and LAN loads, and a green-energy/BMS system with a 12 V input and 5 V rail. These are system examples; the module does not provide the external charger, BMS or communication functions.
Reliability 2600 k hours MTBF, MIL-HDBK-217F at 25°C.
Manufacturer warranty 3 years.
Unit weight 1 g per unit as the catalog PACKING reference.
Reel and carton packing 650 converters per 13-inch reel; one box gross weight 1.04 kg; 2 boxes / 1300 converters per carton, gross weight 2.9 kg.
Packing dimensions Box drawing: 340 × 355 × 43 mm; carton drawing: 125 × 405 × 380 mm. Reel drawing: Ø330 mm outside, Ø100 mm hub, Ø13.15 ±0.35 mm center hole, 30.4 mm maximum width and 2.2 mm local reference.

Manufacturer packing note The catalog states no minimum order quantity is required for sample orders and asks customers to consolidate tape-package orders where possible. Standard tape quantity is 650 pieces; confirm the actual order and packing quantity with the supplier.

Installation and system verification

Complete-system EMC verification Verify EMC with the converter installed in the final equipment and connected to a representative load. Wiring, assembly and the application affect the result.
