Texas Instruments TPS63807YFFR

Overview

TPS63807YFFR from Texas Instruments is a high-efficiency, low-quiescent-current buck-boost DC/DC converter optimized for ultra-compact power solutions requiring output discharge capability. It operates across 1.3 V–5.5 V input and delivers adjustable 1.8 V–5.2 V output with 2-A continuous current (VI ≥ 2.3 V, VO = 3.3 V), 11-µA quiescent current, and 480-µs soft-start ramp time. It targets space-constrained battery-powered systems needing controlled shutdown behavior.

For engineers reviewing the TPS63807YFFR datasheet, TPS63807YFFR pinout, TPS63807YFFR application, or TPS63807YFFR equivalent, key selection criteria include output discharge functionality, 18.5-mm² minimum solution size, WCSP package thermal performance, and seamless buck/buck-boost/boost mode transitions under dynamic input conditions.

Technical Context

The TPS63807YFFR employs a peak-current-mode-controlled, four-switch synchronous architecture that automatically transitions between buck, buck-boost, and boost modes based on real-time VIN–VOUT relationship. Its 3-cycle buck-boost operation maintains high efficiency when input and output voltages are closely matched, minimizing RMS inductor current and conduction losses.

It integrates dual-mode control (PFM for light-load efficiency, forced PWM for low ripple), true shutdown with load disconnect, overtemperature and overvoltage protection, and reverse-current capability. The 500-mV internal feedback reference enables precise output regulation via external resistor divider, while the open-drain PG pin provides system-level power sequencing support.

FAQ

What is the primary function of the TPS63807YFFR?

The TPS63807YFFR is a synchronous buck-boost DC/DC converter that regulates output voltage across an input range narrower than or wider than the set output-enabling stable 1.8 V–5.2 V output from 1.3 V–5.5 V sources. Its defining feature is integrated output discharge during shutdown, making it ideal for systems requiring deterministic power-rail collapse.

Does the TPS63807YFFR support reverse current flow?

Yes, the TPS63807YFFR supports bidirectional current operation. When configured in forced PWM mode (MODE = HIGH), it can deliver reverse current up to –0.9 A, enabling controlled energy transfer from output to input-useful in battery backup or regenerative scenarios where VOUT > VIN.

How does the output discharge feature work in the TPS63807YFFR?

When the EN pin is driven low, the TPS63807YFFR activates an internal discharge switch between VOUT and GND. This actively pulls down the output capacitor voltage to near-zero volts, eliminating residual hold-up voltage without requiring external MOSFETs or timing circuits-critical for functional safety and system-level reset integrity.

What package type and dimensions does the TPS63807YFFR use?

The TPS63807YFFR uses a 3 × 5-ball, 0.4-mm pitch wafer-chip-scale package (WCSP) with nominal dimensions of 2.3 mm × 1.4 mm. This ultra-compact footprint enables total solution sizes as small as 18.5 mm² when paired with 0.47-µH inductors and 22-µF output capacitors.

Can the TPS63807YFFR operate with input voltages below 1.8 V?

The TPS63807YFFR supports input voltages as low as 1.3 V, but requires VIN > 1.8 V to initiate startup. Once running, it continues regulating down to 1.3 V-making it suitable for deep-discharge battery applications where maintaining regulation through full discharge is essential.
