Product details
Overview
TPS62230DRYT 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 2.5 V output voltage, 2.05 V to 6 V input range, and 94% peak efficiency - optimized for Li-ion–powered portable audio and low-power wireless systems.
For engineers reviewing the TPS62230DRYT datasheet, TPS62230DRYT pinout, TPS62230DRYT application, or TPS62230DRYT equivalent, key selection criteria include its 3-MHz switching frequency enabling ultra-small external components (2.2 μH inductor, 4.7 μF capacitor), 22 μA quiescent current in power-save mode, and forced PWM capability via MODE pin - critical for noise-sensitive RF and DSP core supplies.
Technical Context
The TPS62230DRYT implements a hysteretic PWM controller topology supporting both automatic power-save mode (PFM/PWM transition) and forced PWM operation. Its internal 0.7 V reference feeds a precision error comparator that triggers switch pulses based on output voltage deviation and minimum ON-time (135 ns) constraints.
This architecture enables excellent AC load regulation and <90 dB PSRR while maintaining stable operation across –40°C to 125°C junction temperature, with integrated thermal shutdown at 150°C and undervoltage lockout (UVLO) active below 1.8 V (rising threshold).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V - eliminates external feedback resistor network, reduces BOM count and layout area. |
| Switching Frequency | 3 MHz - enables use of 2.2 μH inductors and 4.7 μF ceramic capacitors, minimizing solution size to <12 mm². |
| Max Output Current | 500 mA - supported by internal MOSFETs with 600 mΩ high-side and 350 mΩ low-side RDS(ON) at 25°C. |
| Quiescent Current | 22 μA in power-save mode - extends battery life in always-on portable media devices. |
| Input Voltage Range | 2.05 V to 6 V - supports single-cell Li-ion (2.7–4.2 V), Li-primary, or two-alkaline battery operation. |
| Efficiency | Up to 94% - achieved at medium-to-heavy loads in PWM mode, reducing thermal stress in compact enclosures. |
| Shutdown Current | <1 μA - ensures negligible battery drain during system sleep or standby states. |
Pinout & Package
TPS62230DRYT uses a 6-pin USON (DRY) package measuring 1.45 mm × 1.00 mm × 0.6 mm, with wettable flank terminals for reliable automated optical inspection (AOI) and solder joint quality verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE (Pin 1) | Mode control input | Pull low for automatic PFM/PWM transition; pull high for forced PWM - essential for EMI-sensitive RF sections. |
| SW (Pin 2) | Power switch node | Connects to external inductor; carries high-frequency switching current - requires short, low-inductance PCB trace. |
| VIN (Pin 3) | Main power input | Accepts 2.05–6 V; must be decoupled with ≥2.2 μF ceramic capacitor close to pin for stability and transient response. |
| GND (Pin 4) | Power ground | Low-impedance return path for high-side/low-side MOSFETs and control circuitry - ties to thermal pad for heat dissipation. |
| EN (Pin 5) | Enable input | Active-high logic; must be terminated (no internal pull-down) - enables precise power sequencing with other rails. |
| FB (Pin 6) | Feedback input | Internally connected to 2.5 V divider - no external resistors required; connect directly to output capacitor for regulation accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small solution size | <12 mm² PCB area using only three external components (inductor + two capacitors) - ideal for space-constrained wearables. |
| High PSRR (up to 90 dB) | Rejects input ripple and noise across 10 Hz–1 MHz - enables direct replacement of LDOs in noise-critical analog/RF supply domains. |
| 100% duty cycle capability | Maintains regulation down to VIN – VOUT = 0 V - supports lowest dropout operation during battery end-of-life. |
| Optimized power-save mode | Delivers low output ripple even at light loads with small external components - avoids audible coil whine in portable audio. |
| Thermal shutdown with hysteresis | Triggers at 150°C junction temperature and resets at 130°C - prevents thermal runaway without cycling during sustained overload. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYT | Fixed 1.8 V output; identical 3-MHz frequency, package, and feature set. | Targets lower-voltage DSP or FPGA I/O rails instead of 2.5 V analog/audio domains. | Select when system requires 1.8 V instead of 2.5 V - same footprint and layout, no redesign needed. |
| TPS62235DRYT | Fixed 1.2 V output; 2-MHz switching frequency; same USON-6 package and 500 mA rating. | Suitable for ultra-low-voltage logic or memory supplies where 2.5 V is excessive. | Choose for 1.2 V core rails requiring slightly larger inductors (≥3.3 μH); verify EMI compliance at lower frequency. |

FAQ
What is the fixed output voltage of the TPS62230DRYT?
TPS62230DRYT delivers a factory-trimmed fixed output voltage of 2.5 V with ±2.5% accuracy across –40°C to 125°C junction temperature. This eliminates the need for external feedback resistors and simplifies design for applications requiring precise 2.5 V biasing, such as analog sensor interfaces or reference voltage generation. The TPS62230DRYT achieves this via an internal resistor divider tied to its 0.7 V reference.
Does the TPS62230DRYT require external feedback resistors?
No, the TPS62230DRYT does not require external feedback resistors. It integrates a precision internal resistor divider configured for 2.5 V output, connecting directly to the FB pin. This reduces component count, saves PCB area, and improves regulation accuracy by eliminating resistor tolerance and temperature drift effects - a key advantage over adjustable buck converters like the TPS62231DRYT.
How does the MODE pin affect TPS62230DRYT operation?
The MODE pin on the TPS62230DRYT selects between two operating modes: pulling MODE low enables automatic power-save mode (PFM at light loads, PWM at heavy loads), while pulling MODE high forces continuous PWM operation across all load conditions. This gives designers full control over trade-offs between light-load efficiency and EMI performance - critical for RF-sensitive applications where switching frequency stability matters.
What is the minimum input voltage required for TPS62230DRYT startup?
The TPS62230DRYT requires a minimum input voltage of 2.05 V to initiate startup, as defined by its undervoltage lockout (UVLO) rising threshold. Once enabled, it continues regulating down to the falling UVLO threshold of 1.8 V. This allows reliable operation from partially discharged Li-ion cells (down to ~2.7 V) and two-alkaline batteries, making the TPS62230DRYT well-suited for long-runtime portable devices.
Can the TPS62230DRYT operate with a prebiased output capacitor?
Yes, the TPS62230DRYT supports start-up into a prebiased output capacitor - a critical feature for hot-swap or power-sequencing applications. Its internal soft-start circuit ramps the output from the existing bias voltage to the nominal 2.5 V without causing reverse current flow or output overshoot. This behavior is confirmed in TI's SLVS941G datasheet Section 8.4.2 and ensures safe integration in multi-rail systems where supply turn-on order must be controlled.
