Texas Instruments TPS63001DRCR

Overview

TPS63001DRCR from Texas Instruments is a high-efficiency, single-inductor buck-boost DC-DC converter optimized for battery-powered systems. It delivers up to 1200 mA at 3.3 V output from input voltages ranging from 1.8 V to 5.5 V, supports automatic transition between step-down and boost modes, and achieves up to 96% peak efficiency-enabling compact, long-life power supplies in portable medical devices and smart phones.

For engineers reviewing the TPS63001DRCR datasheet, TPS63001DRCR pinout, TPS63001DRCR application, or TPS63001DRCR equivalent, key selection criteria include its fixed 3.3 V output, 10-pin VSON (3 mm × 3 mm) package, 1.8–5.5 V input range, 1200 mA step-down / 800 mA boost capability, and integrated power-save mode with <50 μA quiescent current.

Technical Context

The TPS63001DRCR employs an average current-mode control architecture with dual feedback loops-fast inner current regulation and outer voltage loop-with input/output voltage feedforward for rapid transient response. Its 4-switch synchronous topology enables seamless buck-to-boost mode transition without external control logic.

It integrates two separate ground domains (GND for control circuitry, PGND for power switches), uses internal 100 mΩ high- and low-side MOSFETs, and features programmable switching frequency (1250–1500 kHz nominal) with synchronization capability via PS/SYNC pin and built-in overtemperature protection (140°C trip, 20°C hysteresis).

FAQ

What is the output voltage configuration of the TPS63001DRCR?

The TPS63001DRCR features a factory-trimmed fixed 3.3 V output. Unlike adjustable variants (e.g., TPS63000), it does not require external feedback resistors-the FB pin is internally connected to VOUT. This simplifies design, reduces component count, and ensures tight output tolerance (±1.5%) across temperature and load without calibration.

Does the TPS63001DRCR support synchronization to an external clock?

Yes, the TPS63001DRCR supports external clock synchronization via the PS/SYNC pin. When driven with a logic-level square wave (1250–1800 kHz), the internal PLL locks to the external frequency-enabling noise-sensitive systems to avoid beat frequencies and simplify EMI filtering. The pin also serves as a power-save mode enable (low = active) or forced PWM control (high = active).

How does the TPS63001DRCR handle input voltage transitions across the 3.3 V output level?

The TPS63001DRCR automatically transitions between buck and boost modes without interruption or control intervention. When VIN > 3.3 V, it operates as a synchronous buck; when VIN < 3.3 V, it seamlessly shifts to synchronous boost-maintaining regulation throughout. This behavior is inherent to its 4-switch topology and average current-mode controller, ensuring stable 3.3 V output from 1.8 V to 5.5 V input.

What thermal considerations apply to the TPS63001DRCR in high-current operation?

The TPS63001DRCR has a junction-to-board thermal resistance (R_θJB) of 21.4°C/W and includes overtemperature protection that disables switching at 140°C with 20°C hysteresis. For 1200 mA continuous output, ensure ≥100 mm² of 2-oz copper connected to the exposed thermal pad (PGND), minimize trace length on L1/L2, and avoid enclosing the IC-achieving ≤45°C temperature rise under typical ambient conditions.

Can the TPS63001DRCR be used with a single 10 µF output capacitor?

Yes, the TPS63001DRCR is qualified for stable operation with a minimum 10 µF ceramic output capacitor (X7R, 6.3 V rating), as shown in the typical application schematic. TI recommends placing it within 2 mm of VOUT and PGND pins. Larger capacitance (e.g., 15–22 µF) further reduces output ripple and improves load-transient response-but 10 µF meets all stability and performance specifications per datasheet.
