Texas Instruments TPS63060DSCR

Overview

TPS63060DSCR from Texas Instruments is a high-input-voltage synchronous buck-boost DC/DC converter with 2-A switch current capability, fixed-frequency 2.4-MHz operation, and automatic buck-to-boost transition. It delivers up to 2 A at 5 V in buck mode (VIN < 10 V), supports 2.5–12-V input, provides power-good signaling, and operates in a thermally enhanced 3 mm × 3 mm WSON-10 package for space-constrained battery-powered systems.

For engineers reviewing the TPS63060DSCR datasheet, TPS63060DSCR pinout, TPS63060DSCR application, or TPS63060DSCR equivalent, key selection criteria include its adjustable output voltage range (2.5–8 V), <30-μA quiescent current in power-save mode, 93% peak efficiency, integrated overtemperature/overvoltage protection, and seamless mode transition near VIN ≈ VOUT.

Technical Context

The TPS63060DSCR implements an average-current-mode control architecture using four internal N-channel MOSFETs-two active per phase-with one switch held on and one held off during each operating mode to minimize switching losses. It maintains regulation across input voltages from 2.5 V to 12 V by automatically selecting buck or boost topology based on real-time VIN/VOUT comparison.

Its control loop integrates dynamic current limiting (ISW = 2.25 A typical), programmable soft-start via controlled current-ramp startup, and power-good monitoring tied directly to output voltage regulation status-not just rail presence. The PS/SYNC pin enables forced PWM mode or external clock synchronization across 2.2–2.6 MHz.

Key Specifications

FAQ

What is the maximum output current capability of the TPS63060DSCR in buck mode?

The TPS63060DSCR delivers up to 2 A at 5 V when operating in buck mode with input voltage below 10 V. This rating assumes proper thermal management using the exposed thermal pad and recommended PCB copper area. At higher ambient temperatures or with insufficient heatsinking, derating applies per the thermal resistance data (RθJA = 48.7°C/W).

Does the TPS63060DSCR support output voltage adjustment, and how is it configured?

Yes, the TPS63060DSCR supports adjustable output voltage from 2.5 V to 8 V via an external resistor divider connected to the FB pin. The internal reference is 500 mV, so VOUT = 500 mV × (1 + R1/R2). For example, R1 = 1 MΩ and R2 = 111 kΩ yields 5 V. The TPS63060DSCR does not support fixed-output versions internally-the TPS63061DSCR is the fixed-5-V variant.

How does the TPS63060DSCR handle transition between buck and boost modes?

The TPS63060DSCR uses Buck-Boost Overlap Control™ to ensure seamless, ripple-minimized transitions. When VIN approaches VOUT, it alternates buck and boost cycles-never operating all four switches simultaneously-and maintains regulation with <5% output deviation. No external control or mode pin is needed; the transition is fully autonomous and occurs within microseconds.

What protection features are integrated into the TPS63060DSCR?

The TPS63060DSCR integrates overtemperature shutdown (140°C trip, 20°C hysteresis), overvoltage protection (12–16 V clamp), undervoltage lockout (1.8–2.2 V threshold), short-circuit current limiting (~2 A average), and load disconnect during shutdown. All protections are hardware-based with no software dependency, ensuring fail-safe behavior in unattended operation.

Can the TPS63060DSCR be synchronized to an external clock, and what is the acceptable frequency range?

Yes, the TPS63060DSCR accepts an external clock signal on the PS/SYNC pin for synchronization. It supports frequencies from 2.2 MHz to 2.6 MHz using a standard CMOS-level clock. The internal PLL tolerates missing pulses without malfunction, making it robust in noisy or intermittent clock environments. Synchronization is optional-leaving PS/SYNC floating or pulled high defaults to free-running 2.4-MHz operation.
