PRODUCT OVERVIEW

What Is the TPS563201DDCR?

TPS563201DDCR is a simple, easy-to-use, 3A synchronous step-down converter from Texas Instruments in a tiny SOT-23 package. The device is designed to operate with minimum external component counts and achieve low standby current[reference:0].

The TPS563201DDCR employs the D-CAP2™ control scheme, providing fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components[reference:1][reference:2]. The device operates in pulse-skip mode (Eco-mode), which maintains high efficiency during light load operation[reference:3][reference:4].

With a wide input voltage range of 4.5V to 17V and an adjustable output voltage from 0.76V to 7V, the TPS563201DDCR is ideal for a variety of applications including digital TV power supplies, high definition Blu-ray players, networking home terminals, digital set-top boxes, and surveillance systems[reference:5][reference:6][reference:7][reference:8]. The device is specified for a junction temperature range of –40°C to 125°C[reference:9].

3A Synchronous Converter Integrated 95mΩ and 57mΩ FETs with 580kHz switching frequency.

D-CAP2™ Control Fast transient response with no external compensation components required.

Pulse-Skip Mode Eco-mode operation maintains high efficiency during light load conditions.

Circuit Considerations for TPS563201DDCR

Output Voltage Configuration

The TPS563201DDCR output voltage is set with an external resistor divider connected to the VFB pin:

Feedback Voltage: VFB threshold is 0.768V typical[reference:45]
Output Voltage Formula: V_OUT = V_FB × (1 + R1 / R2)
Feedback Accuracy: 2% at 25°C[reference:46]
VFB Input Current: 0.1µA maximum[reference:47]

PCB and Power-Supply Guidance

Step-down converter performance depends on layout, bypassing, and component selection:

Input Capacitor: Place a high-quality ceramic capacitor close to the VIN and GND pins
Bootstrap Capacitor: Connect a 0.1µF capacitor between VBST and SW pins[reference:48]
Enable Input: EN is active high; pull up to enable the device[reference:49]
Ground Connection: Connect sensitive VFB to GND at a single point[reference:50]
Thermal Management: θJA = 92.6°C/W for the SOT package[reference:51]
Verify the recommended PCB footprint from the official datasheet before production

Package (6-pin SOT, 1.6mm × 2.9mm)

Control scheme (D-CAP2 with Eco-mode)

Operating temperature (–40°C to 125°C)

Integrated FETs (95mΩ/57mΩ)

Family alternatives: TPS563208DDCR (continuous current mode, no pulse-skip), TPS562201DDCR (2A version), TPS563201DDCT (same, different packaging), TPS563207 (17V, 3A with Eco-mode in SOT-23). For different voltage or current requirements, consider the TPS56220x series (2A) or TPS56420x series (4A). Select based on output current, light-load mode preference, and packaging needs.
