Texas Instruments TPS62A06ADRLR

Overview

TPS62A06ADRLR from Texas Instruments is a 6-A synchronous buck DC/DC converter in SOT563 package, operating from 2.5 V to 5.5 V input and delivering adjustable 0.6 V to VIN output with 1% feedback accuracy, 2.2-MHz switching frequency, and integrated 15-mΩ/10-mΩ MOSFETs. It serves as a high-efficiency point-of-load regulator in space-constrained battery-powered and embedded systems.

For engineers reviewing the TPS62A06ADRLR datasheet, TPS62A06ADRLR pinout, TPS62A06ADRLR application, or TPS62A06ADRLR equivalent, key selection considerations include its PSM/FPWM mode flexibility, power-good signaling, thermal shutdown behavior, and compatibility with low-ESR ceramic output capacitors in compact layouts.

Technical Context

The TPS62A06ADRLR employs peak-current-mode control with adaptive off-time modulation to maintain stable 2.2-MHz operation across varying VIN, VOUT, and load conditions. Its internal soft-start limits inrush current during EN assertion, while HICCUP-mode short-circuit protection triggers after 32 consecutive current-limit events followed by automatic recovery.

It supports 100% duty-cycle low-dropout operation for minimal VIN–VOUT differential under light loads, and integrates active discharge on the SW node to prevent output voltage hold-up. The PG open-drain output provides sequencing-ready status with built-in deglitching and defined logic states for UVLO, thermal shutdown, and enable control.

Key Specifications

Pinout & Package

TPS62A06ADRLR uses a 1.6 mm × 1.6 mm SOT563 (DRL) package with 6 pins and exposed thermal pad (not electrically connected). Pin assignment follows TI-standard top-view orientation.

FAQ

What is the maximum output current capability of the TPS62A06ADRLR?

The TPS62A06ADRLR delivers up to 6 A continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5–5.5 V). Derating applies above ambient temperatures where thermal resistance (RθJA = 137.5°C/W) limits power dissipation - e.g., ~4.5 A at 85°C ambient with standard 2-layer PCB.

Does the TPS62A06ADRLR support forced PWM (FPWM) mode?

No - the TPS62A06ADRLR operates in automatic power-save mode (PSM) at light loads and PWM at medium/heavy loads. The FPWM variant is the TPS62A06A (e.g., TPS62A06ADRLR is PSM/PWM; TPS62A06ADRLR.A is not a valid part number - FPWM version is TPS62A06ADRLR's sibling TPS62A06ADRVR or TPS62A06ADRLR with 'A' suffix in orderable addendum).

How does the power-good (PG) pin function on the TPS62A06ADRLR?

The PG pin on the TPS62A06ADRLR is an open-drain output that pulls low when VOUT falls below 93.5% of target or during EN disable, UVLO, or thermal shutdown. It goes high-impedance when VOUT rises above 96% and remains stable - requiring an external pullup to ≤5.5 V for proper logic-level signaling in power sequencing.

Can the TPS62A06ADRLR start into a pre-biased output capacitor?

Yes - the TPS62A06ADRLR supports pre-bias start-up. When enabled with existing VOUT voltage on the output capacitor, it begins regulation from that bias point and ramps toward the target voltage without causing reverse current or output collapse, making it suitable for hot-swap and multi-rail systems.

What is the recommended output capacitor configuration for 1.2-V/6-A operation with the TPS62A06ADRLR?

For 1.2-V/6-A operation, TI recommends three 22-µF X7R ceramic capacitors (total 66 µF effective) in 0805 case size, placed close to the FB and GND pins. This meets the minimum 45-µF requirement for VOUT ≥ 1.2 V and provides low ESR/ESL for optimal transient response and <10-mV ripple at 2.2-MHz switching.
