Key Features
- 6 A output current capability in a space-saving 6-pin SOT-23 package for high-density power supply designs
- Wide 3 V to 16 V input voltage range covering 5 V, 9 V, and 12 V standard supply rails in a single design
- Voltage-mode PWM control with integrated high-side and low-side MOSFETs reducing external component count
Applications
The TPS566242DRLR is suited for point-of-load DC-DC conversion in networking equipment, industrial controllers, and embedded computing boards where 12 V input must be stepped down to 1.0 V, 1.8 V, or 3.3 V rails at load currents up to 6 A. Its 6-pin SOT-23 footprint enables high-power-density designs with minimal PCB area even when multiple independent rails are required. The 3 V to 16 V input range also makes it compatible with automotive 12 V systems and telecom 48 V-derived intermediate bus rails after pre-regulation.

Frequently Asked Questions
Can TPS566242DRLR supply 6 A continuously from a 12 V input while staying within the SOT-23 package thermal limits?
The TPS566242DRLR can deliver up to 6 A continuous output current, but thermal performance at this level in the SOT-23 package depends on PCB copper area and ambient temperature. With a 12 V input and 1.8 V output (85% efficiency), power dissipation is approximately 0.6 W to 1 W, which requires a thermal ground pour of at least 1 cm² on a 1 oz copper layer to keep junction temperature below 125°C at a 25°C ambient — a consideration that should be verified with a thermal simulation before committing to the SOT-23 footprint at full 6 A load.
For a 12 V to 3.3 V conversion at 4 A, how does TPS566242DRLR compare to a discrete inductor-based solution in terms of BOM size?
The TPS566242DRLR integrates both power MOSFETs and the control circuitry in a single 6-pin SOT-23, requiring only 2 to 3 external capacitors, 1 inductor, and 2 resistors (for feedback) compared to a discrete solution needing a controller IC, 2 separate MOSFET packages, gate drivers, bootstrap capacitor, and compensation network — typically 12 to 18 components. This integration reduces BOM by 8 to 12 parts and shrinks the total solution footprint from approximately 400 mm² to under 150 mm² for a 12 V to 3.3 V, 4 A converter.
Is TPS566242DRLR appropriate for automotive 12 V battery rail applications with load dump transients?
The TPS566242DRLR has a maximum input voltage rating of 16 V, which is sufficient for a regulated 12 V automotive rail but may not cover ISO 7637 load dump transients that can reach 35 V to 40 V on unprotected battery lines. For direct automotive battery connection, an upstream TVS diode rated at 16 V clamp voltage and a series reverse-polarity protection MOSFET are needed to keep the input within the 3 V to 16 V operating range. For applications behind a pre-regulated 12 V bus with proper transient suppression, TPS566242DRLR is a compact and cost-effective solution.
