TPS563207DRLR - 3A 17V Synchronous Buck Converter | TI
MPN: TPS563207DRLR ✓ فعالTPS563207DRLR جائزہ
A DC-DC switching regulator (step-down converter) converts a higher input voltage to a lower regulated output using power MOSFET switches, an inductor, and output capacitors. Synchronous buck converters replace the freewheeling diode with a second MOSFET for higher efficiency. Within the power-management IC hierarchy, the TPS563207 is a monolithic buck regulator with integrated high-side and low-side FETs.
Key features include D-CAP2 mode control for fast transient response and support of low-ESR output capacitors such as specialty polymer and ultra-low-ESR ceramic types. Fixed-frequency operation in Forced CCM (FCCM) mode maintains small output ripple even at light loads. The 3-A rating with integrated FETs minimizes external component count, and the tiny SOT-563 footprint suits dense PCB layouts. The device is specified from -40C to +125C junction temperature.
Internally, D-CAP2 control combines a wide-bandwidth error amplifier with an adaptive on-time generator, enabling near-constant frequency operation and quick response to load steps with minimal output capacitance. Internal compensation and soft-start reduce design effort and board area.
Typical applications include 5 V and 12 V rail point-of-load regulation for networking equipment, SSDs and storage, industrial PCs, FPGA/ASIC auxiliary rails, and consumer electronics. The 17-V maximum input covers 12-V buses with margin.
Design tip: choose the inductor value and output capacitors per the TI datasheet equations; FCCM mode favors low ripple, while the 0.806-V feedback reference supports low-voltage cores. Verify thermal performance, as the small DRL package dissipates heat mainly through the PCB.

Networking Equipment Point-of-Load
The TPS563207DRLR suits 12-V bus powered networking switches, routers, and access points that need compact 3-A local rails for PHYs, MACs, and memory. Its 4.3-V to 17-V input accepts 12-V rails directly, and the 0.806-V adjustable output covers 1.0-V, 1.2-V, 1.8-V, and 3.3-V needs via resistor dividers. D-CAP2 control delivers fast transient response during bursty packet traffic, while FCCM mode keeps ripple low at light loads. The 1.6-mm x 1.6-mm SOT-563 package fits dense port-side layouts.

SSD and Storage Systems
Solid-state drives and storage controllers require tiny, efficient point-of-load converters; the TPS563207DRLR answers with a 1.6-mm x 1.6-mm SOT-563 footprint and integrated synchronous FETs rated 3 A. The 12-V input matches SATA/NVMe drive power, and D-CAP2 mode supports ultra-low-ESR ceramic output capacitors, minimizing BOM area. FCCM operation keeps output ripple small during idle and active states, protecting noise-sensitive controller and NAND rails. Its -40C to +125C junction range covers drive thermal environments.

Industrial Automation Control
In factory automation, PLC I/O modules and sensor interfaces often distribute 12 V or 24 V (with pre-regulation) and need robust local step-down conversion. The TPS563207DRLR provides 3 A from a 4.3-V to 17-V input with -40C to +125C junction specification, suiting harsh cabinet environments. D-CAP2 control tolerates low-ESR ceramic capacitors, improving reliability where electrolytics would age. The simple external component count of typically an inductor plus input/output capacitors accelerates design cycles for industrial OEMs.

FPGA and ASIC Auxiliary Rails
FPGA and ASIC designs need multiple auxiliary rails (1.0 V to 3.3 V) with fast load-step response for I/O banks, transceivers, and configuration logic. The TPS563207DRLR adjustable output from 0.806 V and D-CAP2 transient performance handle switching surges, while the 3-A rating covers mid-current rails. FCCM mode maintains predictable ripple for analog-heavy auxiliary supplies. Small size allows the converter to sit close to the load, reducing parasitic inductance and improving transient response.

Consumer Electronics Power
Set-top boxes, smart displays, and consumer appliances use 12-V adapters and need low-cost, small-footprint buck conversion. The TPS563207DRLR offers competitive sub-$0.70 unit pricing as of 2026-08-29, a 6-pin SOT-563 package, and minimal external parts, reducing BOM cost and board area. Its FCCM mode yields low output ripple for sensitive audio/video circuitry, while the 3-A capability covers HDMI, SoC, and wireless module rails with margin. The -40C to +125C junction spec adds robustness.

Battery-Powered and Portable Devices
Portable instruments and battery packs with multi-cell stacks (4S-3S lithium ranges near 12-17 V) benefit from the TPS563207DRLR 17-V maximum input. The synchronous architecture achieves high efficiency at the 3-A level, extending battery runtime versus nonsynchronous designs. D-CAP2 mode maintains stability with compact ceramic output capacitors, and the tiny SOT-563 package suits handheld enclosures. Designers should manage light-load behavior: FCCM trades standby efficiency for low ripple.

ڈیزائن نوٹس
Keep the power loop (VIN capacitor, integrated FETs, SW pin, inductor, output capacitor) as tight as possible. Place a 10-uF ceramic input capacitor within 2 mm of VIN and GND, and the output capacitor close to the inductor. Connect the BOOT capacitor (0.1 uF typical) directly between BOOT and SW. Because the SOT-563 package dissipates heat through the PCB, use at least a small ground plane and thermal vias under the GND pin; per TI datasheet layout guidelines, the DRL package theta_JA depends heavily on copper area.
Select the inductor using the TI datasheet equations, typically 1.5 uH to 4.7 uH for common 1.0-V to 3.3-V outputs. Verify peak current rating exceeds the switch current limit plus margin, and check RMS ripple current. Use X7R/X5R ceramic output capacitors with DC-bias derating accounted for - effective capacitance can drop 50% at rated voltage, affecting stability of the D-CAP2 loop.
Do not exceed the 17-V absolute input rating; 24-V industrial buses require a front-end regulator. Ensure EN is not left floating above its absolute maximum if driven from a divider. The FCCM mode keeps switching at light load - this lowers ripple but raises standby quiescent draw; if battery life dominates, consider eco-mode family members like TPS563201 instead. Verify FB divider current stays low to avoid draining low-power rails.
