Texas Instruments TPS562207DRLR

Overview

TPS562207DRLR from Texas Instruments is a 2-A synchronous buck DC-DC converter in SOT563 (DRL) package, featuring integrated 140-mΩ high-side and 84-mΩ low-side MOSFETs, D-CAP2™ control mode for fast transient response, 580-kHz fixed switching frequency, and 0.804-V to 7-V adjustable output voltage - used in digital TV power rails and smart speaker core supplies.

For engineers reviewing the TPS562207DRLR datasheet, TPS562207DRLR pinout, TPS562207DRLR application, or TPS562207DRLR equivalent, key selection criteria include input voltage range (4.3 V–17 V), forced continuous conduction mode (FCCM), ±2% FB accuracy at 25°C, hiccup-mode overcurrent protection, and pre-bias soft-start capability.

Technical Context

The TPS562207DRLR implements adaptive on-time D-CAP2™ control with internal ramp compensation, enabling stable operation with ultra-low-ESR ceramic or polymer output capacitors without external compensation. Its FCCM operation ensures fixed 580-kHz switching frequency and minimal output voltage ripple across load conditions.

Protection architecture includes cycle-by-cycle valley-current limiting, non-latching thermal shutdown (160°C trip, 135°C recovery), non-latching output undervoltage protection (65% of nominal), and UVLO with 4.3-V turn-on/3.6-V shutdown hysteresis - all implemented in a single-die monolithic structure with integrated power FETs.

FAQ

What is the recommended input capacitor configuration for TPS562207DRLR?

TI recommends a minimum 10-µF X5R/X7R ceramic capacitor placed adjacent to the VIN and GND pins, plus an additional 0.1-µF ceramic capacitor directly between VIN and GND for high-frequency filtering. The TPS562207DRLR datasheet specifies these values to suppress input ripple and ensure stable operation across the 4.3–17 V input range. Layout best practices require short, wide traces and multiple vias to the ground plane.

Does TPS562207DRLR support output voltage sequencing with other rails?

Yes, TPS562207DRLR supports controlled sequencing via its EN pin: applying a delayed enable signal coordinates startup with other regulators. The device also features pre-bias soft-start, allowing it to safely regulate into an already charged output without reverse current or overshoot - a critical capability for TPS562207DRLR in multi-rail systems like digital STBs and networking SoCs.

What is the maximum achievable output voltage accuracy across temperature for TPS562207DRLR?

The TPS562207DRLR maintains ±2.5% total output voltage accuracy over –40°C to 125°C junction temperature, combining initial FB reference tolerance (±2%), temperature drift (±0.5% max), and resistor divider error. This is confirmed in Section 6.5 of the TPS562207DRLR datasheet, where V_FBTH is specified as 788–820 mV across temperature - enabling reliable core rail regulation in thermally demanding environments.

Can TPS562207DRLR operate with 100% duty cycle?

No, TPS562207DRLR cannot achieve 100% duty cycle due to bootstrap capacitor recharge requirement. The minimum off-time is 220 ns (typical), limiting maximum duty cycle to approximately 98% at 580 kHz. For near-unity conversion ratios, TI recommends verifying dropout behavior in the TPS562207DRLR electrical characteristics table - where V_IN(MIN) = 4.3 V ensures regulation down to V_OUT = 0.804 V.

How does the hiccup-mode overcurrent protection behave during sustained overload on TPS562207DRLR?

Under sustained overload, TPS562207DRLR enters hiccup mode: it shuts down for 18 ms (T_{HICCUP_RE}), then attempts restart. If overload persists, this cycle repeats indefinitely. During each active period, cycle-by-cycle current limiting holds peak inductor current at ~3.1 A (I_{OCL_L_SOURCE}). This behavior is documented in Section 6.5 and protects both TPS562207DRLR and downstream circuitry without latching or requiring manual reset.
