Description

Product Overview

The TPS6209733RWKR from Texas Instruments is the tape-and-reel version of the TPS6209733RWKT, a 3A synchronous step-down converter with 3.3V fixed output in a VQFN-6 (2x2mm) package. Identical in functionality, it is packaged for automated SMT assembly.

Key Specifications

Input Voltage 2.3 V to 6 V
Output Voltage 3.3 V (fixed)
Output Current 3 A
Switching Frequency 2.5 MHz (typical)
Quiescent Current 17 uA (typical)
Operating Temperature -40C to +125C

Features

  • 3A output current in tiny 2x2mm VQFN-6 package
  • 3.3V fixed output eliminates external feedback resistors
  • DCS-Control topology for fast transient response
  • 2.5MHz switching frequency for small inductors
  • 17uA quiescent current in power-save mode
  • 100% duty cycle mode for lowest dropout

Applications

  • Single-cell Li-Ion to 3.3V regulation
  • Portable instruments and handheld devices
  • USB-powered 3.3V supplies
  • Wearable and IoT device power management

The TPS6209733RWKR from Texas Instruments is the tape-and-reel packaged version of the TPS6209733RWKT, a 3A synchronous step-down converter with a fixed 3.3V output in an ultra-compact VQFN-6 (2x2mm) package. Functionally identical to the tray version, this variant is supplied on tape and reel for automated SMT assembly. The device operates from 2.3V to 6V input with DCS-Control topology for fast transient response and seamless PWM/PFM mode transition. The 2.5MHz switching frequency enables tiny external components, and the 17uA power-save quiescent current preserves battery life. The fixed 3.3V output eliminates external feedback resistors for minimal solution size.

The TPS6209733RWKR uses the same DCS-Control architecture as the TPS6209733RWKT. (1) DCS-Control: Combines voltage-mode control with a fast output voltage comparator for immediate transient response. (2) PWM Mode: Fixed 2.5MHz switching at loads above power-save threshold. (3) Power-Save Mode: PFM operation with 17uA quiescent current at light loads. (4) Seamless Transition: Smooth mode switching without output voltage disturbances. (5) 100% Duty Cycle: High-side MOSFET held continuously on when VIN approaches VOUT.

Pin Name Type Function
1 VIN Power Input supply (2.3-6V)
2 GND Ground Ground
3 EN Input Enable (active high)
4 SW Output Switch node (connect to inductor)
5 VOUT Power Regulated 3.3V output
6 PG Output Power good (open-drain)
  • Single-cell Li-Ion to 3.3V regulation for automated SMT assembly
  • Portable instruments and handheld devices with tape-and-reel packaging
  • USB-powered 3.3V supplies with DCS-Control fast transient
  • Wearable and IoT device power management in VQFN-6
