Product details
Overview
TPS62233DRYT from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter in a 1 mm × 1.5 mm USON-6 package, delivering up to 500 mA output current with fixed 3.0 V output, 2.05–6 V input range, and 94% peak efficiency. It serves as a high-efficiency replacement for LDOs in space-constrained portable audio and low-power wireless systems.
For engineers reviewing the TPS62233DRYT datasheet, TPS62233DRYT pinout, TPS62233DRYT application, or TPS62233DRYT equivalent, key selection criteria include its 3-MHz switching frequency enabling ultra-small 1 μH inductor + 4.7 μF capacitor filtering, 22 μA quiescent current in power-save mode, and forced-PWM capability via MODE pin for noise-sensitive RF/audio rails.
Technical Context
The TPS62233DRYT implements a hysteretic PWM controller topology supporting both automatic PFM/PWM transition and user-enforced PWM mode. Its internal 0.7 V reference feeds a precision feedback loop tied to the FB pin, enabling ±2.5% output voltage accuracy across –40°C to 125°C junction temperature.
It integrates dual MOSFETs (600 mΩ high-side, 350 mΩ low-side typical RDS(ON)), minimum ON/OFF times of 135 ns / 40 ns, and thermal shutdown at 150°C with 20°C hysteresis - all optimized for stable operation with minimal external components in battery-powered applications.

FAQ
What is the fixed output voltage of the TPS62233DRYT?
The TPS62233DRYT has a factory-trimmed fixed output voltage of 3.0 V, achieved using an internal resistor divider referenced to a 0.7 V bandgap. This eliminates external feedback components and ensures ±2.5% accuracy over –40°C to 125°C junction temperature, making it ideal for powering 3.0 V logic, RF ICs, and analog circuitry without calibration.
Does the TPS62233DRYT require external feedback resistors?
No, the TPS62233DRYT does not require external feedback resistors. It features an internal fixed-resistor divider that sets the output to 3.0 V. The FB pin connects directly to the output capacitor for regulation, simplifying design and reducing BOM count - a key advantage over adjustable buck converters requiring two precision resistors.
How does the MODE pin affect TPS62233DRYT operation?
The MODE pin on the TPS62233DRYT selects between automatic PFM/PWM mode (MODE = GND) and forced PWM mode (MODE = VIN). In PFM mode, quiescent current drops to 22 μA for light loads; in forced PWM, switching remains continuous at ~3 MHz, enabling predictable EMI filtering - essential for noise-sensitive RF or audio subsystems powered by the TPS62233DRYT.
What is the minimum input voltage required for TPS62233DRYT startup?
TPS62233DRYT requires a minimum input voltage of 2.05 V to initiate startup, as defined by its undervoltage lockout (UVLO) rising threshold. It remains functional down to the falling UVLO threshold of 1.8 V, allowing operation across the full discharge curve of Li-primary or two-alkaline-cell sources - a critical capability confirmed in the TPS62233DRYT datasheet's recommended operating conditions.
Can the TPS62233DRYT operate with a 1 μH inductor and 4.7 μF output capacitor?
Yes, the TPS62233DRYT is explicitly optimized for use with a 1 μH inductor and 4.7 μF ceramic output capacitor - enabling total solution area under 12 mm² and height under 0.6 mm. This combination achieves stable regulation, low output ripple, and >90% efficiency across load currents up to 500 mA, as validated in TI's typical application schematics and layout guidelines for the TPS62233DRYT.
