概述

Description

The B0505LS-1W is a compact isolated DC-DC converter module rated at 1 W. It takes a DC input and provides a regulated 5 V output with galvanic isolation between input and output, allowing separate ground references and helping to block noise and ground loops in mixed‑voltage systems.
Typical features (vendor vary): small form factor (SMD or through‑hole), fixed 5 V output, input range around a few volts up to ~9 V, isolation often in the 1 kV+ range, basic protection (short‑circuit/overload), and operation over a wide temperature range (often −40 to +85 °C). Efficiency is commonly in the 60–75% range, with low standby loss.
Common uses include isolated digital and microcontroller rails in embedded systems, telecom, and industrial controls where a compact, low‑noise 5 V supply is needed.
Note: exact specifications (input range, isolation voltage, efficiency, package, and pinout) vary by vendor and variant. Consult the specific datasheet for your B0505LS‑1W product.

Features

Here are the typical features of a B0505LS-1W (1W isolated DC-DC converter) in concise form:
- 1W isolated DC-DC converter with 5V output
- Input: 4.5–9V DC (5V nominal)
- Output: regulated 5V, up to ~200 mA
- Input–output isolation: typically around 1.5 kV DC min
- High efficiency (roughly 60–75%)
- Wide operating temperature: about -40°C to +85°C
- Compact surface-mount (low-profile) package
- Protections: short-circuit/overload protection; thermal shutdown
- Low output ripple and good regulation across load
- RoHS-compliant; suitable for industrial/telecom applications
Note: exact numbers vary by vendor and revision. Check the specific datasheet for precise input range, isolation voltage, efficiency, and temperature range.

Package

The B0505LS-1W is supplied in an 8-pin single in-line (SIP-8) through-hole package (single‑row SIP module).

Pinout

B0505LS-1W is a 4‑pin isolated 1 W DC‑DC converter. Pin functions (viewing the module marking side up, pins down, left→right):
- Pin 1: Vin +
- Pin 2: Vin − (input ground)
- Pin 3: Vout +
- Pin 4: Vout − (output ground / isolated)

Manufacturer

- Manufacturer: Murata Power Solutions (a brand of Murata Manufacturing Co., Ltd.)
- What kind of company: A Japanese multinational electronics company that designs and manufactures electronic components and power solutions, including DC-DC converters and power modules, with global operations.

Application

B0505LS-1W is a compact isolated DC-DC converter (5V output, 1W). Typical applications:
- Industrial control, instrumentation, and data acquisition
- Embedded systems and IoT boards
- Telecom/network equipment
- Medical devices (non-critical isolation)
- Point-of-sale and small electronic systems
Use anywhere a small, galvanically isolated 5V rail is needed from a higher-voltage supply.
