Product details
Overview
TPS61230DRCR 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 internal switch, operates at 2 MHz switching frequency, and features adjustable output voltage via external resistor divider. It is used in USB power supplies and portable power banks requiring high efficiency and compact footprint.
For engineers reviewing the TPS61230DRCR datasheet, TPS61230DRCR pinout, TPS61230DRCR application, or TPS61230DRCR equivalent, key selection considerations include its 2.3–5.5-V input range, 2.5–5.5-V programmable output, 96% peak efficiency, integrated power good (PG) output, and load disconnect during shutdown - all in a 3 mm × 3 mm VSON-11 package.
Technical Context
The TPS61230DRCR employs quasi-constant on-time valley current mode control with automatic transition between PWM (2 MHz) and PFM modes for optimal light-load efficiency. Its control architecture enables fast line/load transient response without external compensation.
It integrates undervoltage lockout (UVLO) with adjustable hysteresis via HYS pin, programmable soft start via SS pin, output overvoltage protection (OVP) with 5.7–6.2 V threshold, and thermal shutdown at 150°C. The EN pin supports logic-level enable/disable with 1.11–1.23 V threshold and true load disconnect in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports full discharge of single-cell Li-Ion (2.7–4.2 V) and regulated 3.3-V rails. |
| Output Voltage Range | 2.5 V to 5.5 V - set externally via FB pin resistor divider; enables flexible system-level voltage scaling. |
| Max Output Current | 2.1 A at 5 V - achievable with 3.3-V input; determined by 4.0–6.0 A switch valley current limit and thermal design. |
| Switching Frequency | 2 MHz nominal - enables use of small 1.0 µH inductors and low-ESR ceramic capacitors for minimal board area. |
| Peak Efficiency | 96% - measured at VIN = 3.6 V, VOUT = 5.0 V, IOUT = 1 A; reduces thermal stress in space-constrained designs. |
| Quiescent Current | 35–60 µA - enables >100-hour standby in battery-powered devices without significant drain. |
| Shutdown Current | 1.5 µA typical - ensures near-zero battery leakage when disabled, critical for always-on backup systems. |
Pinout & Package
TPS61230DRCR is housed in a thermally enhanced 11-pin VSON package (3.00 mm × 3.00 mm × 0.9 mm), with exposed thermal pad for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1,2) | Power switch node | Connects to drain of internal 5-A synchronous MOSFETs; requires low-inductance layout to minimize EMI and switching losses. |
| VOUT (Pins 3,4) | Boost output | High-current output path; dual pins reduce IR drop and improve thermal performance under 2.1-A loads. |
| PG (Pin 5) | Power Good indicator | Open-drain output signals valid regulation (VOUT ≥ 95% nominal); requires external pull-up ≤5.5 V. |
| SS (Pin 6) | Soft-start control | Capacitor-connected pin sets ramp time; internal 5-µA bias current enables precise startup timing control. |
| FB (Pin 7) | Feedback input | Senses output voltage divider ratio; determines regulated output; must be connected for adjustable operation. |
| HYS (Pin 8) | EN hysteresis programming | Configures UVLO hysteresis using external resistors; prevents oscillation during input brownout conditions. |
| EN (Pin 9) | Enable logic input | Active-high digital control; 1.11–1.23 V threshold enables direct MCU GPIO interfacing without level shifters. |
| VIN (Pin 10) | Input supply | Primary power input; accepts 2.3–5.5 V; decoupling capacitor placement critical for stability. |
| GND (Pin 11) | Power ground | Reference for all internal circuits; connects to thermal pad; must be low-impedance plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 5-A power switch | Eliminates need for external MOSFETs and gate drivers; supports 2.1-A continuous output at 5 V with 3.3-V input. |
| Programmable soft start | SS pin controls output voltage ramp rate via external capacitor; prevents inrush current and stabilizes downstream LDOs. |
| Power Good (PG) output | Provides system-level power sequencing feedback; open-drain structure allows easy interfacing with 1.8-V/3.3-V logic. |
| Load disconnect in shutdown | True isolation between VIN and VOUT; blocks reverse current and eliminates battery drain in off-state. |
| Adjustable input UVLO with hysteresis | HYS pin enables custom brownout recovery thresholds; avoids repeated cycling during marginal input conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61231DRCR | Includes output capacitor discharge (RDIS ≈ 200 Ω); same pinout and electrical specs otherwise. | Required where safe discharge of VOUT is mandated (e.g., hot-plug interfaces, safety-critical reset paths). | Select TPS61231DRCR only if output discharge functionality is explicitly needed; otherwise TPS61230DRCR offers identical performance with lower cost. |
| TPS61088RHLR | Higher 10-A switch, 2.7–12-V input, fixed 5-V option; larger 14-pin WQFN package; no HYS/SS pins. | Suitable for higher-current (>3 A) or wider-input applications; lacks programmable UVLO and soft start. | Choose TPS61088RHLR only when >2.1-A output or >5.5-V input is required; TPS61230DRCR remains optimal for compact 2.1-A, 3.3-V-to-5-V designs. |
Compared with TPS61231DRCR, TPS61230DRCR omits output discharge but retains identical efficiency, regulation accuracy, and thermal performance - making it preferred for cost-sensitive, non-safety-critical boost applications. Against TPS61088RHLR, TPS61230DRCR provides superior integration (HYS, SS, PG) and smaller footprint for sub-2.1-A systems.

FAQ
What is the maximum output current capability of the TPS61230DRCR?
The TPS61230DRCR delivers up to 2.1 A at 5 V output when supplied from a 3.3-V input, limited by its 4.0–6.0 A internal switch valley current limit and thermal design. At lower input voltages (e.g., 2.3 V), maximum output current decreases due to duty cycle constraints and junction temperature rise; derating curves in the datasheet must be consulted for specific VIN/VOUT combinations.
Does the TPS61230DRCR support adjustable output voltage?
Yes, the TPS61230DRCR supports fully adjustable output voltage from 2.5 V to 5.5 V using an external resistor divider connected to the FB pin. The feedback reference voltage is 1.007 V (typical) in PFM mode and 1.0 V (typical) in PWM mode. Unlike the fixed-output TPS61232DRCR, the TPS61230DRCR requires no internal resistor network and relies entirely on external components for voltage setting.
How does the TPS61230DRCR handle light-load efficiency?
The TPS61230DRCR automatically enters power save mode (PFM) at light loads, reducing switching frequency and quiescent current to maintain >85% efficiency down to 10-mA loads. Its 35–60 µA IQ and 1.5 µA shutdown current minimize battery drain in standby, enabling extended runtime in always-on portable devices without compromising heavy-load performance.
What is the purpose of the HYS pin on the TPS61230DRCR?
The HYS pin on the TPS61230DRCR allows external programming of the enable comparator's hysteresis and adjusted UVLO threshold using two resistors. This enables customized power-up/down sequencing and prevents oscillation during input voltage brownouts. The HYS pin is left floating if standard 2.1–2.2 V UVLO behavior is acceptable; it must not be shorted to GND or VIN.
Can the TPS61230DRCR be used in zero-duty-cycle mode?
Yes, the TPS61230DRCR automatically enters zero-duty-cycle mode when VIN is within 0.24 V of VOUT (e.g., VIN = 4.76 V for 5-V output). In this mode, the high-side rectifying switch remains continuously on, providing low-loss conduction with minimal dropout - effectively acting as a low-RDS(on) pass element. This extends usable battery life by avoiding switching losses near full charge.
