B0505LS-1W

B0505LS-1W is a compact isolated DC-DC converter module rated for about 1 watt of output power. It provides a galvanically isolated 5 V rail from a low-voltage input, making it suitable for powering circuits from a higher-level or noisy supply while keeping grounds separate.
Typical features (from common datasheets):
- Input: around 4.5–5.5 V DC (single-ended)
- Output: fixed 5.0 V, up to roughly 200 mA (≈1 W total)
- Isolation: around 1.5 kV DC between input and output
- Efficiency: commonly in the 60–75% range depending on conditions
- Temperature range: usually -40°C to +85°C (industrial) or similar
- Package: small surface-mount, 8-pin footprint (built-in switcher)
Applications: miniaturized, isolated supply rails for microcontrollers, sensors, instrumentation, telecom, and embedded systems.
Notes: check the exact pinout, footprint, and temperature range on the specific datasheet for your lot, as there can be minor variations between revisions.

Equivalent products are other 1W, isolated 5V→5V DC‑DC converters with the same package/pinout. Typical sources: Murata (NME0505 family), RECOM (R05‑0505S family), Traco Power (TMA/TMV 0505 series) and Cincon (CM0505 family). Always verify pinout, input range, isolation rating and thermal/EMC specs before substituting.

Here are the typical features of B0505LS-1W:
- 1 W isolated DC-DC converter
- 5 V input to 5 V output (regulated)
- Isolation: commonly around 1.5 kV DC (input–output)
- High efficiency (roughly in the 70–85% range)
- Wide operating temperature: typically -40 to +85 °C
- Small, encapsulated package (compact SIP-4 style)
- Short-circuit/overload protection
- RoHS-compliant and safety-certified (UL/IEC where applicable)
- No external components required (fully enclosed)
Note: exact input range, pinout, and ratings can vary by revision—please consult the specific datasheet for precise specs.

Pin count: 4 (SIP-4)
Function: The B0505LS-1W is a 1 W isolated DC‑DC converter (5 V input → 5 V output). The four pins serve the input and isolated output rails: Vin+ (V in), Vin– (ground/return), Vout+ (isolated +V out) and Vout– (isolated output return). It provides galvanic isolation between input and output and low-noise regulated 5 V output.

Manufacturer: Murata (Murata Power Solutions / Murata Manufacturing Co., Ltd.)
What kind of company: Murata is a Japanese multinational electronic‑components manufacturer. Its businesses include ceramic capacitors, sensors and RF/wireless modules, and a dedicated power‑solutions division (Murata Power Solutions) that designs and makes power‑conversion products such as isolated DC‑DC converters (like the B0505LS‑1W), AC‑DC modules and related power electronics.

B0505LS-1W is a compact isolated DC-DC converter (about 1 W, 5 V output). Common application areas:
- Industrial automation: isolated rails for controllers, sensors, I/O modules
- Instrumentation/data acquisition: isolates measurement circuits from power noise
- Medical equipment: low-power isolated subsystems
- Telecom/networking: isolated logic/interface rails in routers, switches, modems
- Embedded systems/consumer electronics: small-form-factor isolation on PCBs
- USB peripherals/POS devices: isolated power for interface ICs and display modules
Note: suitable for any application needing a compact, galvanically isolated 5 V supply.

The B0505LS-1W is supplied in a 4-pin single in-line (SIP-4) through‑hole plastic module package (SIP/DIP‑style).
