Typical Applications
TPS562201DDCT is suitable for 6 applications: 12V Point-of-Load Power Supply, Networking and Telecom Equipment, Industrial Automation Systems, Set-Top Boxes and Digital TV, Embedded Microcontroller Boards, Server and Data Center Auxiliary Rails.
12V Point-of-Load Power Supply
The TPS562201DDCT converts a 12V intermediate bus directly to low-voltage rails (0.768V-7V) at up to 2A. The 17V input maximum provides headroom on 12V rails, while the 580 kHz switching frequency keeps inductor size small for dense point-of-load placement. D-CAP2 control delivers fast transient response during load steps, and Eco-mode pulse skipping maintains efficiency at light standby loads common in always-on infrastructure equipment.
Recommended
Networking and Telecom Equipment
Switches, routers, and optical modules use the TPS562201DDCT to power ASICs, PHYs, and memory from 12V backplane supplies. The 2A rating covers typical MAC/PHY rails, integrated synchronous MOSFETs eliminate the external Schottky diode for a compact BOM, and low standby current plus Eco-mode reduce power draw during idle link states. The 6-pin SOT-23-Thin package fits the tight board spacing typical of SFP and small switch modules.
Recommended
Industrial Automation Systems
In PLC I/O modules, motor-drive control boards, and factory sensors, the TPS562201DDCT generates 5V, 3.3V, or 1.8V logic rails from 12V or 24V-derived buses. The -40C to +125C junction rating supports industrial ambient extremes, and D-CAP2's ceramic-capacitor compatibility suits high-vibration environments where electrolytics are avoided. Its simplicity (internally compensated) shortens design cycles for derivative product variants.
Recommended
Set-Top Boxes and Digital TV
Consumer STB and DTV platforms use multiple TPS562201DDCT channels to power SoC core, I/O, and memory rails from a 12V adapter input. Fast D-CAP2 transient response handles core-voltage load spikes during video decoding, the 580 kHz frequency avoids audible-band noise, and Eco-mode meets standby power regulations when the system is off but the adapter remains plugged in.
Recommended
Embedded Microcontroller Boards
MCU and DSP evaluation and production boards use the TPS562201DDCT as a compact 2A point-of-load for 3.3V logic and 1.2V core supplies. Its minimal external component count keeps small boards simple, and the adjustable 0.768V floor supports modern low-voltage cores. D-CAP2 stability with ceramic output capacitors simplifies layout near sensitive analog sections on mixed-signal MCU boards.
Recommended
Server and Data Center Auxiliary Rails
Server backplane designs use the TPS562201DDCT for housekeeping rails such as fan controllers, EEPROMs, and management logic from 12V distribution. The wide 17V input tolerates backplane transients, Eco-mode keeps standby power low when the server is idle, and the small SOT-23 footprint fits crowded management sections of server motherboards and storage controller cards.

Key Differentiators
- Full 2A output in 6-pin package (vs TPS561201DDCR)
- D-CAP2 fast transient control (vs TPS54202DDCR)
- Simplicity with internally compensated loop (vs TPS563201DDCR)
Design Notes
Place the input ceramic decoupling capacitor as close as possible to VIN (pin 2) and GND (pin 5). Keep the SW (pin 6) to inductor connection short and tight to minimize the high-frequency switching loop area and EMI. The BOOT capacitor should be placed directly adjacent to BOOT and SW pins per the TI datasheet layout guidelines.
Verify thermal performance at full 2A load: use the junction temperature rating of -40C to +125C and the SOT-23-6 theta_JA from the datasheet thermal information table to compute worst-case Tj at your ambient. At high input voltage (17V) with low output voltage, duty-cycle limits reduce effective duty and inductor RMS current rises - verify inductor saturation current is above the peak current limit.
D-CAP2 stability depends on output capacitance and ESR within the recommended range in the datasheet application section - excessive ceramic-only output capacitance can destabilize the loop. The 0.768V feedback reference sets the minimum output; ensure the resistor divider uses 1% tolerance resistors for output accuracy. Do not exceed 7V output due to minimum off-time constraints.
Compliance Information
RoHS compliant per TI/DigiKey listing. Not an AEC-Q100 automotive part; TI quality pages should be consulted for REACH and halogen-free declarations.
