Detailed Description

Wide-input, non-synchronous buck regulator with integrated high-side switch. Delivers up to 500 mA output current from 9 V to 75 V input. Adjustable output from 2.5 V to 73 V. Compact 8-VSSOP package, surface-mount. Industrial temperature range −40°C to +125°C (TJ). RoHS3 compliant. Ideal for stepping down high-voltage rails to low-voltage loads with simple external components.

RoHS: ROHS3 compliant

Key Advantages

Handles high input voltages up to 75 V, making it robust for industrial and telecom rails

Simple, cost-effective design thanks to non-synchronous architecture and minimal external components

Compact 8-pin package saves PCB space

Adjustable output supports many rails with one part

Reliable protection features (current limit, thermal shutdown, UVLO) help protect your system

Stable operation across wide temperature range for harsh environments

Packaging

Type: 8-VSSOP (also known as MSOP-8); supplier device package: 8-VSSOP

Delivery: Tape & Reel (TR), compliant with EIA-481 for automated assembly

Material: Molded epoxy over copper leadframe; standard lead finish for SMT reflow

Size: Body width approximately 3.00 mm (0.118"); low-profile height typical of MSOP; pin pitch typically 0.65 mm

Pin configuration: Standard 8-pin buck regulator layout (VIN, SW, GND, FB, SS/soft-start, EN/enable, and timing/comp/control pins). Refer to the datasheet for the exact pin names and mapping.

Thermal characteristics: Junction operation −40°C to +125°C; thermal resistance depends on PCB copper area and airflow. Use large ground copper and proper vias for heat spreading.

Electrical properties summary: 9–75 V input, 2.5–73 V adjustable output, up to 500 mA load, non-synchronous buck, one output, positive configuration

Lifecycle

Status: Active and widely used; not nearing discontinuation based on current industry availability

Equivalent or alternative models:

- Texas Instruments LM5017: 100 V input capable buck regulator, up to ~600 mA, synchronous, 8-pin package; better efficiency at higher Vin

- Texas Instruments LM5160/LM5160A: 65–100 V synchronous buck controllers/regulators, higher efficiency; various current options

- Texas Instruments LM5161: 100 V synchronous buck regulator, up to 1 A; for higher current needs

- Texas Instruments LM5018: 100 V buck regulator, up to ~300 mA; similar wide-Vin but lower current

- Texas Instruments LM5008/LM5009: Wide-Vin buck regulators with lower current (100–150 mA) if your load allows

- Analog Devices (LT) LT3971: Up to 60 V input, 1.2 A buck regulator; if you need more current at moderate Vin

- Analog Devices (LT) LT3985: 60 V input buck regulator; compact alternatives for mid-voltage rails

- ON Semiconductor NCP3065/NCP3066: Wide-Vin regulators for simpler, low-current designs
