Overview
The TMS38010NL is a high-performance synchronous step-down DC/DC converter manufactured by Texas Instruments. It belongs to the SIMPLE SWITCHER family and features an input voltage range of 4.2V to 80V with a continuous output current capability of 1A. The device integrates internal compensation, pseudo-random spread spectrum for EMI reduction, and adjustable switching frequencies between 200kHz and 2.2MHz. It operates within a temperature range of -40°C to +125°C and utilizes an 8-pin HSOIC PowerPAD package.
Feature Summary
- Wide input voltage range supporting industrial applications
- Integrated synchronous rectification for high efficiency
- Adjustable switching frequency with external clock synchronization
- Built-in protection against overcurrent, short circuits, and thermal overload
Applications
- Industrial power systems
- Mobile hybrid electric vehicle (MHEV) systems
- Electric vehicle (EV) power distribution
- Point-of-load regulation modules
Procurement Notes
Verify the specific suffix 'NL' against official datasheets to confirm package type and temperature grade. Ensure compatibility with required input voltages up to 80V. Confirm lead times as delivery schedules may vary. Validate that the selected component meets all functional safety documentation requirements if used in safety-critical designs.
Selection Notes
Select this component when a wide input voltage range and compact solution size are required. Consider the integrated spread spectrum feature for strict EMI constraints. Evaluate the need for external clock synchronization versus internal frequency adjustment. Ensure the 1A output current meets the load requirements without exceeding thermal limits in the chosen enclosure.
Part Context
This part is part of the LMR38010 series, designed for robust performance in demanding environments. It simplifies design through internal compensation and minimal external component count. The device supports both PFM and forced PWM modes for optimized efficiency across varying load conditions.
Replacement Considerations
The LM380N/NOPB is listed as a potential replacement in some contexts, though it is an audio amplifier and functionally distinct. Verify electrical compatibility carefully. No direct pin-to-pin digital equivalent is confirmed in the provided data.
