Product details
Overview
TPS61230DRCT from Texas Instruments is a synchronous step-up DC-DC converter optimized for single-cell Li-Ion battery systems and 3.3-V rail-to-5-V power conversion. It delivers up to 2.1 A at 5 V output from a 3.3-V input, integrates a 5-A switch, operates at 2 MHz, and features adjustable output voltage via external FB divider. It is used in USB power supplies and portable power banks requiring high efficiency and compact footprint.
For engineers reviewing the TPS61230DRCT datasheet, TPS61230DRCT pinout, TPS61230DRCT application, or TPS61230DRCT equivalent, key selection considerations include its 2.3–5.5-V input range, 2.5–5.5-V programmable output, 96% peak efficiency, 1.5-µA shutdown current, and integrated power good (PG) and enable hysteresis (HYS) functions.
Technical Context
The TPS61230DRCT employs quasi-constant on-time valley current mode control with automatic transition between PWM (2 MHz) and PFM modes. Its architecture supports zero-duty-cycle operation when VIN approaches VOUT, enabling seamless regulation near input-output crossover.
It integrates dual MOSFETs with 75-mΩ typical RDS(on) per side, undervoltage lockout with adjustable hysteresis via HYS pin, and soft-start timing controlled by external capacitor on SS pin. The PG open-drain output asserts low below 90% of nominal VOUT and releases above 95%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports direct connection to single-cell Li-ion (2.7–4.2 V) or regulated 3.3-V rails without pre-regulation. |
| Output Voltage Range | 2.5 V to 5.5 V - set externally via resistor divider on FB pin; enables flexible system-level voltage scaling. |
| Max Output Current | 2.1 A at 5 V - achievable with 3.3-V input; limited by 5-A internal switch and thermal design. |
| Switching Frequency | 2 MHz - enables use of small 1-µH inductors and low-ESR ceramic capacitors for minimal board area. |
| Peak Efficiency | 96% - measured at 3.6-V input, 5-V output, 1-A load; reduces thermal load in space-constrained applications. |
| Shutdown Current | 1.5 µA typical - ensures battery longevity during system sleep; load fully disconnected from VIN. |
| Feedback Reference | 1.000 V ±1.5% - precise internal reference enables accurate output regulation across temperature and line. |
Pinout & Package
TPS61230DRCT is housed in a thermally enhanced 3 mm × 3 mm × 0.9 mm VSON-11 package with exposed thermal pad (DRC suffix), supporting high-power density and efficient PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1,2) | Power switch node | Connects to drain of internal high-side and low-side MOSFETs; requires low-inductance layout to minimize switching noise. |
| VOUT (Pins 3,4) | Boost output power rail | Delivers regulated output; pins are paralleled for lower resistance and improved current handling. |
| PG (Pin 5) | Power good status indicator | Open-drain output asserting low when VOUT < 90% of target; requires external pull-up to ≤5.5 V. |
| SS (Pin 6) | Soft-start timing control | Capacitor-connected node sets ramp time; internal 5-µA bias current defines startup slope. |
| FB (Pin 7) | Output voltage feedback | Resistor divider input for adjustable output; referenced to 1.000 V internal reference. |
| HYS (Pin 8) | Enable hysteresis programming | Configures EN threshold hysteresis using external resistors; prevents chatter during power-rail transitions. |
| EN (Pin 9) | Logic enable input | Active-high control: ≥1.19 V enables, ≤1.14 V disables; must be terminated-never left floating. |
| VIN (Pin 10) | Main input supply | Accepts 2.3–5.5 V; feeds internal bias circuitry and power stage; requires local 22-µF ceramic decoupling. |
| GND (Pin 11) | Power ground return | Primary ground reference for all analog and power circuits; tied directly to thermal pad for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output voltage | Set from 2.5 V to 5.5 V using external resistor divider on FB pin-supports multiple system rails from one BOM. |
| Integrated power good (PG) | Open-drain output with 90%/95% VOUT thresholds-enables reliable power sequencing and fault detection in multi-rail systems. |
| Programmable enable hysteresis | HYS pin allows custom EN rising/falling thresholds-eliminates need for external supervisor IC in brown-in/brown-out scenarios. |
| Load disconnect in shutdown | True isolation between VIN and VOUT with <1.5-µA quiescent current-prevents battery drain in standby mode. |
| Overvoltage protection (OVP) | 6.0-V DC OVP threshold with 0.15-V hysteresis-protects downstream 5-V logic from transient overvoltage events. |
Applications
| USB Power Supply | Portable Power Bank |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61231DRCT | Same pinout and core specs, but adds output capacitor discharge (RDIS ≈200 Ω) during shutdown. | Required where residual VOUT hold-up must be actively cleared (e.g., safety-critical reset sequences). | Select TPS61231DRCT only if output discharge is mandatory; otherwise TPS61230DRCT offers identical boost performance with simpler biasing. |
| MT9700-5.0 | Fixed 5-V output, no FB/HYS/SS pins; 1.8-A max output; 1.5-MHz switching; different package (QFN-12). | Suitable for cost-sensitive, fixed-voltage applications without sequencing or hysteresis requirements. | Choose MT9700-5.0 for simplified BOM and lower unit cost where adjustability and advanced enable control are unnecessary. |
Compared with TPS61231DRCT, TPS61230DRCT omits output discharge but retains full programmability and hysteresis control-ideal for general-purpose boost where fast startup and precise enable behavior outweigh discharge needs. Versus MT9700-5.0, it trades fixed output for flexibility and higher current capability in the same footprint class.

FAQ
What is the minimum input voltage required for TPS61230DRCT to regulate a 5-V output?
The TPS61230DRCT requires a minimum input voltage of 2.3 V to initiate regulation. However, to sustain 5-V output at full 2.1-A load, input must remain ≥3.3 V under worst-case conditions. Below ~3.0 V, output current capability degrades due to reduced duty cycle margin and increased conduction losses-verified in TI's SLVSAQ2C datasheet Figure 8 (Switch Valley Current Limit vs Input Voltage).
Does TPS61230DRCT support automatic transition between PWM and PFM modes?
Yes, the TPS61230DRCT automatically transitions between 2-MHz PWM mode (moderate-to-heavy loads) and pulse-frequency-modulation (PFM) mode (light loads) without external control. This preserves >90% efficiency down to 1-mA loads, as confirmed in Figure 6 (Quiescent Current vs Input Voltage) and Section 8.4.2 of the SLVSAQ2C datasheet.
Can the TPS61230DRCT be used with a fixed 5-V output without external resistors?
No-the TPS61230DRCT requires an external resistor divider on the FB pin to set output voltage. For fixed 5-V operation, use the pin-compatible TPS61232DRCT, which integrates an internal 5-V feedback divider. Attempting to short FB to VOUT on TPS61230DRCT results in unregulated, unstable output per Section 6 (Pin Functions) and Figure 12 (Typical Application).
What is the purpose of the HYS pin on the TPS61230DRCT?
The HYS pin on the TPS61230DRCT programs hysteresis for the EN comparator, allowing custom rising/falling enable thresholds (e.g., 1.19 V ON / 1.14 V OFF). This prevents oscillation during slow-rising input rails and enables precise power-up sequencing-detailed in Equation 3 and Figure 10 of the SLVSAQ2C datasheet.
Is thermal performance data available for the TPS61230DRCT in its VSON-11 package?
Yes-TI specifies RθJA = 49.1°C/W, RθJC(bottom) = 4.5°C/W, and ψJB = 23.8°C/W for the DRC package in Section 7.4. These values assume standard JEDEC 2-layer board layout; actual junction temperature rise can be calculated using TJ = TA + (Pdiss × RθJA), where Pdiss derives from efficiency curves in Figure 1 (Efficiency vs IOUT).
