Key Features
- Wide input voltage range of 3 V to 16 V with 12 V nominal covers standard 5 V, 9 V, and 12 V supply rails in one design
- Integrated voltage-mode PWM control with internal power MOSFETs reduces external component count to an inductor and filter capacitors
- Compact 6-pin SOT-23 flat-lead (DRL) package minimizes PCB area for point-of-load regulators in space-constrained boards
- RoHS-compliant Pb-free construction (JESD-609 e3) supports lead-free manufacturing for consumer and industrial applications
Applications
TPS564242DRLR is ideal for point-of-load DC-DC conversion in industrial IoT nodes, consumer electronics, and telecom line cards where a 12 V bus must be stepped down to 3.3 V or 1.8 V logic rails with high efficiency. Its wide 3 V to 16 V input range makes it directly usable on 5 V USB power banks, 9 V adapters, and 12 V automotive accessory rails without redesign. The tiny DRL package and low external component count simplify layout for multi-rail power trees on dense PCBs, including single-board computers and sensor hubs.

Frequently Asked Questions
What input voltage range does TPS564242DRLR support and which supply rails is it compatible with?
The TPS564242DRLR accepts an input voltage range of 3 V to 16 V with a nominal design point of 12 V, making it compatible with 5 V USB, 9 V adapter, 12 V automotive accessory, and 15 V industrial bus supplies in a single design. This wide range eliminates the need for a separate pre-regulator in multi-rail systems, reducing BOM cost and board area by at least 1 component per supply rail.
How does the voltage-mode PWM control topology of TPS564242DRLR affect output ripple and transient response?
Voltage-mode PWM control in TPS564242DRLR provides a fixed switching frequency, which makes output voltage ripple predictable and filter design straightforward using a standard LC output filter. Compared to hysteretic regulators, the fixed-frequency approach simplifies EMI filtering and allows precise output capacitor selection to meet less than 1% output ripple at full load, important for noise-sensitive ADC or RF supply rails operating at 3.3 V.
What is the package footprint of TPS564242DRLR and how does it fit into a compact point-of-load PCB layout?
TPS564242DRLR uses a 6-pin SOT-23 flat-lead (DRL) package with a body size of approximately 1.6 mm x 2.9 mm, one of the smallest packages for an integrated synchronous buck converter with internal MOSFETs. This allows the complete point-of-load regulator circuit, including input and output capacitors and the inductor, to fit within a 5 mm x 8 mm board area on a 2-layer PCB.
When should a designer choose TPS564242DRLR over a larger SOIC-8 buck controller for a 12 V to 3.3 V conversion?
TPS564242DRLR is the better choice when board space is the primary constraint and output current requirements are within the device rated range, because its 6-pin DRL package is at least 50% smaller than a standard SOIC-8 footprint occupying roughly 19 mm squared. A larger SOIC-8 controller may be preferred when output current exceeds the TPS564242DRLR rating, when custom gate drive timing is needed, or when the design requires external power MOSFETs rated for higher than 16 V input.
