- Synchronous buck topology in a compact 6-pin flat-lead (SOTFL) package reduces external component count and minimizes PCB footprint for dense board designs
- RoHS-compliant (Pb-free, JESD-609 e3) construction meets global environmental regulations for consumer, industrial, and communications end-equipment
Applications
The TPS565242DRLR is used in point-of-load DC/DC conversion for embedded computing boards, IoT gateway modules, and industrial sensor nodes that step down a 12 V or 5 V bus to lower logic supply voltages using a 3 V to 16 V input range. Its voltage-mode PWM control scheme provides stable regulation over wide load current swings, making it suitable for powering DSPs, FPGAs, and microcontrollers in telecom line cards and factory automation equipment. The small 6-pin flat-lead package enables high-density power supply designs in space-constrained applications such as motor drive auxiliary supplies and portable test instruments.

Frequently Asked Questions
What input voltage range does the TPS565242DRLR support, and which power bus architectures are compatible?
The TPS565242DRLR accepts input voltages from 3 V to 16 V with a nominal 12 V operating point, making it directly compatible with standard 5 V USB power buses, 9 V wall adapters, and 12 V industrial distribution rails. This 13 V operating window allows a single regulator design to cover multiple system variants without redesigning the power stage for each input voltage.
How does the voltage-mode PWM control of TPS565242DRLR benefit noise-sensitive analog and RF subsystem designs?
Voltage-mode PWM control produces a fixed switching frequency with predictable harmonic content, allowing the PCB designer to place switching noise harmonics away from sensitive analog or RF bands using a simple LC output filter. Unlike hysteretic converters, the TPS565242DRLR maintains constant frequency regulation, simplifying EMI filter design and enabling the output ripple to be bounded to less than 50 mV peak-to-peak with a properly sized inductor and output capacitor.
For a compact IoT node powered from a 12 V rail, how does the TPS565242DRLR's package size compare to older SOIC-8 buck regulators?
The TPS565242DRLR uses a 6-pin flat-lead (SOTFL) package with a land pattern smaller than 10 mm², compared to a standard SOIC-8 footprint of approximately 30 mm². This 3x reduction in package area is significant for IoT nodes where the power section competes with RF antennas and sensor circuitry for PCB real estate, enabling designs that maintain the 12 V to sub-3.3 V conversion in less than one-third the board space.
What procurement considerations apply when designing with TPS565242DRLR in high-volume industrial production?
The TPS565242DRLR ships in tape-and-reel (DRLR suffix) format optimized for automated SMT pick-and-place with a 15-year YTEOL longevity rating from Texas Instruments, confirming long-term availability. Its Pb-free, RoHS-compliant status satisfies IEC 62368-1 and IEC 61010 industrial equipment directives, reducing compliance documentation burden. Distributors typically maintain 12 V input-range synchronous buck regulators in this package on bonded inventory for short lead times.
