Detailed Description

High-voltage, non-synchronous step-down (buck) DC-DC regulator

Input voltage range 6 V to 75 V

Adjustable output 2.5 V up to near the input voltage (limited by duty cycle and losses)

600 mA continuous output current

Single output, positive configuration

Internal high-side power switch, external Schottky diode required

10-pin VSSOP (also known as 10-MSOP/10-TFSOP, 3.0 mm body width)

Surface-mount, RoHS3 compliant

Operating junction temperature range -40°C to +125°C

Key Features

Wide input operating range 6–75 V for 12 V, 24 V, and 48 V systems

600 mA output capability for point-of-load rails

Adjustable output voltage 2.5 V to near VIN via resistor divider

Buck topology, non-synchronous (no internal low-side FET)

Integrated high-side switch for compact design

Enable/UVLO pin for on/off control and input undervoltage protection

Soft-start control for controlled inrush current (via external capacitor)

Cycle-by-cycle current limiting for protection

Thermal shutdown for device protection

Good line/load regulation and stable operation with proper compensation

Low shutdown current for energy saving

Pb-free “NOPB” suffix, RoHS3 compliant

Key Advantages

Handles harsh, high-voltage inputs up to 75 V with margin

Simple, robust design with few external parts

Small 10-VSSOP package saves PCB area

Flexible output setting and sequencing with EN and soft-start pins

Proven reliability for industrial and infrastructure power rails

Easy to design, wide ecosystem of TI reference designs and app notes

Packaging

Shipment type Tape & Reel TR for automated placement

Package and case 10-VSSOP also labeled 10-MSOP or 10-TFSOP 3.00 mm width

Material Lead-free, RoHS-compliant mold compound over copper leadframe

Size Body width approx 3.0 mm 0.118 inch typical; low-profile MSOP-class outline; fine-pitch leads

Lifecycle

Status Active and broadly supported by Texas Instruments

Not nearing discontinuation based on current industry status

Equivalent or alternative models to consider verify specs and pinouts carefully

- TI LM5007MM/NOPB 6–75 V input, ~300 mA output, non-synchronous, smaller current

- TI LM5008MM/NOPB 6–75 V input, ~350 mA output, non-synchronous

- TI LM5005 6–75 V input, up to ~2.5 A output, non-synchronous, larger package

- TI LM5017 9–100 V input, 600 mA output, non-synchronous, different package WSON and pinout

- TI LM5019 9–100 V input, 600 mA output, synchronous, higher efficiency, different package

- TI LM5160/LM5161 3.8–65 V input synchronous bucks, various currents, higher efficiency, different pinouts
