Description

DPB09W8-05 — Regulated SIP DC/DC converter

The MEAN WELL DPB09W8-05 is an isolated, regulated dual-output SIP8 DC/DC converter in the 9 W DPB09W8 family. It accepts 9–75 V DC and supplies ±5 V DC relative to Common, with 0–800 mA in magnitude on each rail. No minimum load is required. Remote ON/OFF control is provided; apply the specified thresholds and load derating.

Electrical specifications

Model and output configuration	DPB09W8-05; isolated, regulated dual-output DC/DC converter in a SIP8 package with industry-standard pinout.
Output voltage	±5 V DC relative to Common. Simultaneous rails: +5 V and −5 V.
Output current range	0–800 mA in magnitude on each rail. No minimum load is required.
Output power and current limit	9 W series; the selected output is limited to 0–800 mA in magnitude on each rail, corresponding to 8 W calculated from voltage × current across both rails. Observe the series total-power ceiling and thermal derating; rounded current figures do not increase the rating.
Input operating range	9–75 V DC, 8:1 input-range family; the selection table lists nominal 12, 24, 36, 48 and 72 V systems.
Input current	10 mA at no load; 397 mA at full load under the general measurement conditions.
Typical efficiency	82% under the general measurement conditions.
Series efficiency capability	The family offers efficiency up to 87% across its models; use the selected model’s typical value above.
Maximum capacitive load	330 µF for each output.
Input surge limit	100 V DC for 100 ms maximum.
Input filter and recommended fuse	Pi network; a 2 A slow-blow fuse is recommended.
Output voltage accuracy	±2%.
Ripple and noise	The catalog specifies 100 mVp-p maximum for 3.3–9 V outputs and 1% of output voltage, peak-to-peak maximum, for 12–24 V outputs. Confirm the applicable category for this dual-output model. Measured at 20 MHz using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation	±0.5%, measured from low line to high line at rated load.
Load regulation	±0.5%, measured from 0% to 100% rated load.
Switching frequency	300 kHz minimum.
General measurement conditions	Unless otherwise specified: normal 24 V DC input, rated load, 25°C and 70% RH ambient.
Cross regulation	±5% at 25–100% load, applicable only to dual-output models.

Protection, control and thermal operation

Short-circuit protection	Continuous short-circuit protection with automatic recovery.
Overload protection	120–230% of rated output power; automatic recovery after the fault is removed.
Typical under-voltage lockout	Start-up: 8.8 V DC; shutdown: 8 V DC.
Remote control	Referenced to −Vin. Power ON: above 2.5 V DC, up to 30 V DC, or open circuit. Power OFF: below 1 V DC or shorted to −Vin.
Operating and case temperature	−40 to +90°C ambient, subject to derating; case temperature +115°C maximum.
Cooling and load derating	Natural convection: 100% load from −40 to +55°C; 50% at +80°C and 30% at +90°C. Follow the applicable curve between these points; the specified operating ceiling is +90°C.
Working humidity	20–90% RH, non-condensing.
Storage conditions	−55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient	0.05%/°C over 0 to +70°C.
Soldering conditions	At 1.5 mm from the case: 3–5 seconds at 260°C maximum.
Vibration	10–500 Hz, 2 G; 10 minutes per cycle, for 60 minutes along each of the X, Y and Z axes.
Remote-control interface	Control input: pin 3; control common: pin 1. Converter shutdown idle current: 10 mA. Compatible with CMOS or open-collector TTL control.

Isolation, EMC and reliability

Applicable safety approvals	EAC TP TC 020/2011 approved.
Isolation withstand voltage	Input to output: 1.5 kV DC.
Isolation resistance	Input to output: 1000 MΩ at 500 V DC, 25°C and 70% RH.
Typical isolation capacitance	80 pF.
EMC emission	BS EN/EN 55032 (CISPR 32): conducted N/A; radiated Class A with external components.
ESD immunity	BS EN/EN 61000-4-2: Level 3, ±8 kV air.
Radiated RF immunity	BS EN/EN 61000-4-3: Level 2, 3 V/m.

Conducted RF immunity	BS EN/EN 61000-4-6: Level 2, 3 V e.m.f.
MTBF	Greater than 300 Khrs, MIL-HDBK-217F at 25°C.
Manufacturer warranty	3 years.
Magnetic-field immunity	BS EN/EN 61000-4-8: Level 1, 1 A/m.
EMC suggestion circuit	The radiated Class A recommendation uses nominal input and full load. C2 is across the module input; C3 links module-side +Vin to +Vout and C4 links −Vin to −Vout. The circuit also draws C1 across the supply and L1 in the positive input line, but marks both X in the component table.
Radiated Class A external components	C2 = 2.2 µF / 100 V MLCC. C3 and C4 are each labelled “102/3 kV”; confirm the intended capacitor-code specification before selection. C1 and L1 are marked X.

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. Follow the model's specified EMC conditions and any required external components; the linked EMI testing guidance does not certify the finished equipment.
