Texas Instruments TPS63010YFFT

Overview

TPS63010YFFT from Texas Instruments is a highly efficient, single-inductor buck-boost DC/DC converter with synchronous 2-A switches, fixed-frequency PWM control, and automatic seamless transition between buck and boost modes. It delivers up to 1200 mA at 3.3 V in step-down mode (VIN = 3.6 V–5.5 V), supports 2 V–5.5 V input range, and operates in a compact 20-pin DSBGA (2.126 mm × 1.922 mm) package for space-constrained portable battery-powered systems.

For engineers reviewing the TPS63010YFFT datasheet, TPS63010YFFT pinout, TPS63010YFFT application, or TPS63010YFFT equivalent, this device is selected for its high-efficiency operation across wide VIN–VOUT differentials, integrated overvoltage/overtemperature protection, low-quiescent-current power-save mode, and compatibility with single-cell Li-ion or multi-cell alkaline/NiMH battery inputs in portable medical, audio, and communications devices.

Technical Context

The TPS63010YFFT implements a fixed-frequency average current-mode controller using four internal N-channel MOSFETs - two active switching, one permanently on, one permanently off - enabling continuous conduction mode with minimized RMS current and switching losses. Its dual-ground architecture (GND for logic, PGND for power) isolates control circuitry from high-current paths.

It features programmable output voltage via external resistor divider on FB, undervoltage lockout (1.5–1.8 V on VINA), output overvoltage protection (6.5 V threshold), and thermal shutdown (140 °C with 20 °C hysteresis). The PS pin enables/disables power-save mode, while SYNC allows external clock synchronization from 2.2 MHz to 3 MHz.

FAQ

What is the function of the VINA pin on the TPS63010YFFT?

The VINA pin supplies power to the control circuitry of the TPS63010YFFT and features an independent undervoltage lockout (UVLO) threshold of 1.5–1.8 V. It must be connected to the same source as VIN unless isolated biasing is used; separating VINA from VIN allows partial operation during input droop, improving system robustness in brownout conditions. The TPS63010YFFT draws only 50 μA from VINA in normal operation.

Can the TPS63010YFFT be used with a single 3.7-V Li-ion battery to generate 3.3 V?

Yes - the TPS63010YFFT is explicitly designed for this use case. As the battery discharges from 4.2 V to ~2.5 V, the TPS63010YFFT automatically transitions between buck mode (VIN > VOUT) and boost mode (VIN < VOUT) while maintaining regulated 3.3 V output. At 3.6 V input, it delivers up to 1200 mA; at 2.4 V input, it sustains 800 mA - making it ideal for single-cell Li-ion systems requiring full-depth discharge utilization.

Does the TPS63010YFFT support external synchronization, and what is the valid frequency range?

Yes, the TPS63010YFFT supports external clock synchronization via the SYNC pin. It accepts input frequencies from 2.2 MHz to 3.0 MHz, allowing EMI reduction through frequency dithering or alignment with system clocks. When not in use, SYNC must be tied to GND to prevent noise coupling; leaving it floating may cause erratic operation. The internal oscillator operates at 2.4 MHz nominal.

How does the TPS63010YFFT handle short-circuit conditions on the output?

The TPS63010YFFT implements hardware-based short-circuit protection that limits average switch current to ~400 mA if VOUT fails to rise above 1.2 V during startup or drops to 0 V during operation. This soft current limiting prevents thermal runaway and allows safe recovery once the fault clears. Unlike latch-off schemes, the TPS63010YFFT continues monitoring and resumes regulation automatically without requiring a reset.

Is the TPS63010YFFT pin-compatible with TPS63011YFFT or TPS63012YFFT?

No - while all three share the same YFF DSBGA-20 package and pinout, the TPS63010YFFT is the adjustable-output variant requiring an external FB resistor divider, whereas TPS63011YFFT and TPS63012YFFT are fixed-output versions with internal dividers and VSEL-controlled dual-voltage options. Using TPS63010YFFT in place of a fixed-output variant requires redesigning the feedback network and confirming VSEL logic level handling.
