Texas Instruments TPS6208833YFPT

Overview

TPS6208833YFPT from Texas Instruments is a 3-A, fixed 3.3-V synchronous step-down converter in a 0.8mm × 1.2mm × 0.5mm wafer chip-scale package (YFP), featuring DCS-Control topology, 4 MHz switching frequency, 1% output voltage accuracy, and 4 µA quiescent current - designed for space-constrained embedded power rails in portable electronics.

For engineers reviewing the TPS6208833YFPT datasheet, TPS6208833YFPT pinout, TPS6208833YFPT application, or TPS6208833YFPT equivalent, key selection criteria include its 2.4V–5.5V input range, 100% duty cycle low-dropout operation, active output discharge, power-good signal, and thermal/short-circuit protection - all in a 0.5-mm height WCSP suitable for ultra-thin SSDs and camera modules.

Technical Context

The TPS6208833YFPT operates in PFM/PWM hybrid mode: it maintains 4 MHz PWM at medium-to-heavy loads and seamlessly transitions to power-save mode at light loads, preserving >90% efficiency down to 1 mA. Its DCS-Control architecture eliminates the need for an external VOS pin while delivering excellent load transient response and <1% output voltage regulation error across temperature and line variation.

Internally integrated 26 mΩ high-side and 26 mΩ low-side MOSFETs enable high-efficiency conversion with minimal external components. The device supports 100% duty cycle operation for lowest dropout, includes hiccup-mode short-circuit protection with 32-cycle fault latching, and features a dedicated open-drain power-good (PG) output with 92–110% voltage window detection and 100-µs blanking on rise.

FAQ

What is the maximum continuous output current of the TPS6208833YFPT?

The TPS6208833YFPT delivers up to 3 A continuous output current under recommended operating conditions (TJ ≤ 85°C for YFP package). At junction temperatures above 85°C, lifetime derating applies per TI's datasheet Section 6.3. The internal 26-mΩ MOSFETs support this rating with appropriate PCB copper area and airflow.

Does the TPS6208833YFPT require external feedback resistors?

No, the TPS6208833YFPT does not require external feedback resistors. It is a fixed 3.3-V output variant with internal resistor divider connected to the FB pin; the FB pin must be directly connected to the output capacitor. This eliminates tuning errors and saves board space versus adjustable versions.

What package type and dimensions does the TPS6208833YFPT use?

The TPS6208833YFPT uses the YFP (DSBGA, 6-pin) wafer chip-scale package with nominal dimensions of 0.8 mm × 1.2 mm × 0.5 mm and 0.4 mm ball pitch. Its low-profile construction supports embedding and ultra-thin end-equipment designs such as camera modules and wearables.

How does the power-good (PG) function work on the TPS6208833YFPT?

The TPS6208833YFPT's PG pin is an open-drain output that goes high-impedance when FB voltage is between 96% and 105% of 3.3 V (i.e., 3.17–3.47 V), and pulls low when outside that window. It requires an external pullup resistor to ≤5.5 V and sinks up to 1 mA, enabling rail sequencing with other converters.

Can the TPS6208833YFPT operate with input voltage below 3.3 V?

Yes, the TPS6208833YFPT supports input voltages as low as 2.4 V and enters 100% duty cycle mode when VIN drops within ~10% above VOUT (i.e., ~3.63 V for 3.3 V out), maintaining regulation down to approximately 3.6 V. Below that, output voltage follows input minus conduction losses until dropout occurs.
