What are the key features of LM5008ASD/NOPB?
- Wide 6 V to 95 V input voltage range with 48 V nominal operation serves industrial bus voltages including 24 V, 48 V, and telecom -48 V rails
- 350 mA output current with adjustable output from 2.5 V via external resistor divider covers a broad range of system supply requirements
- Voltage-mode PWM control with internal gate driver simplifies external component selection and ensures stable regulation over load and line variations
- Tiny 8-pin LLP (3 mm × 3 mm) package minimizes board footprint in space-constrained industrial and rack-mount power supply modules
What is LM5008ASD/NOPB used for?
LM5008ASD/NOPB is used in industrial equipment powered from 24 V or 48 V buses—such as PLCs, factory automation controllers, and building automation nodes—where a compact step-down regulator must supply 3.3 V or 5 V rails at up to 350 mA. Its wide 95 V input tolerance also suits telecom equipment operating from -48 V bus supplies and automotive applications with high transient voltages up to 95 V. The adjustable output from 2.5 V makes it a flexible single-IC solution for powering microcontrollers, FPGAs, and communication interfaces across diverse industrial designs.

Frequently Asked Questions
What input voltage range does LM5008ASD/NOPB support, making it suitable for 48 V industrial bus power supplies?
LM5008ASD/NOPB accepts input voltages from 6 V to 95 V, with 48 V nominal operation, directly supporting 24 V and 48 V industrial bus systems as well as telecom -48 V supplies and automotive loads with transients up to 95 V.
What output current and minimum output voltage can LM5008ASD/NOPB deliver in an adjustable step-down configuration?
LM5008ASD/NOPB delivers up to 350 mA continuous output current with output voltage adjustable from 2.5 V to near input voltage using a simple external resistor divider, covering common system rails like 3.3 V, 5 V, and 12 V.
How does LM5008ASD/NOPB compare in board space to through-hole step-down solutions for the same power level?
LM5008ASD/NOPB in the 8-pin LLP package measures 3 mm × 3 mm, occupying approximately 9 mm² of board area—80% less than a typical TO-220 or DIP-8 package—enabling much denser PCB layouts in rack-mount and panel-mount industrial designs.
What control technique does LM5008ASD/NOPB use, and how does voltage-mode PWM affect output filter design?
LM5008ASD/NOPB uses voltage-mode PWM (pulse width modulation) control, which requires an LC output filter typically with a 10–47 µH inductor and 10–47 µF capacitor, providing predictable second-order filter design and good audio-frequency noise rejection in sensitive analog circuits.
