Product details
Overview
TPS61093DSKT from Texas Instruments is a fixed-frequency, current-mode boost converter IC with integrated 20-V/1.1-A power switch, input/output isolation FET, and power diode. It operates from 1.6 V to 6 V input, delivers up to 17 V output (e.g., 15 V @ 50 mA), achieves up to 88% efficiency, and features programmable soft start, overload/overvoltage protection, and load discharge on shutdown - used in portable medical and OLED power supplies.
For engineers reviewing the TPS61093DSKT datasheet, TPS61093DSKT pinout, TPS61093DSKT application, or TPS61093DSKT equivalent, key selection considerations include its 1.2-MHz switching frequency, 0.5-V feedback reference, 2.5 mm × 2.5 mm WSON-10 package with thermal pad, isolation FET functionality, and compatibility with single-cell Li-ion or dual alkaline battery inputs.
Technical Context
The TPS61093DSKT uses current-mode PWM control with fixed 1.2-MHz oscillator frequency and built-in slope compensation to prevent subharmonic oscillation. Its functional block integrates a 20-V N-channel MOSFET (RDS(on) = 0.4 Ω typ), isolation FET (RDS(on) = 4 Ω typ at VO = 5 V), and internal power diode - enabling input-output disconnection during shutdown and overload events.
It implements undervoltage lockout (1.55 V threshold), thermal shutdown (150°C), cycle-by-cycle overcurrent protection (1.1-A peak limit), and output overvoltage protection (19-V threshold with 0.6-V hysteresis). The FB pin regulates output via 0.5-V reference, while SS pin controls soft-start timing using an external RC network charged by 5-μA internal current source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.6 V to 6 V - supports single Li-ion (3.0–4.2 V), two alkaline (2.4–3.2 V), or regulated 3.3/5-V rails. |
| Output Voltage Range | Up to 17 V - programmable via resistor divider on FB pin; 15-V output validated at 50-mA load. |
| Switching Frequency | 1.2 MHz (typ) - enables compact external components (e.g., 4.7-μH inductor, 4.7-μF input cap). |
| Feedback Reference | 0.5 V ±1% - sets output voltage accuracy; requires external R1/R2 divider (e.g., R2 = 10 kΩ for 50-μA bias). |
| Peak Switch Current | 1.1 A - limits inductor peak current; protects against short-circuit and overload conditions. |
| Isolation FET RDS(on) | 4 Ω (max at VO = 5 V) - provides input-output disconnect during shutdown; adds ~200-mV drop at 50 mA. |
| Shutdown Current | <1 μA - minimizes battery drain in standby; triggered by 1-ms low pulse on EN pin. |
Pinout & Package
TPS61093DSKT is housed in a thermally enhanced 2.5 mm × 2.5 mm × 0.8 mm WSON-10 package with exposed thermal pad (soldered to PCB ground plane). Pin numbering follows top-view DSK package layout with pin 1 at bottom-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal ground reference | Primary return path for all internal circuits; must connect to low-impedance PCB ground plane and thermal pad. |
| VIN (Pin 2) | Main power input | Accepts 1.6–6 V supply; powers internal bias circuitry and switch driver; requires ≥4.7-μF ceramic input capacitor. |
| CP1, CP2 (Pins 3, 4) | Flying capacitor terminals | Connect external 10-nF ceramic capacitor to enable internal charge pump for gate drive of isolation FET. |
| EN (Pin 5) | Enable control input | Active-high logic; pulls low for ≥1 ms to enter ultra-low-power shutdown (<1 μA); internal 800-kΩ pull-down. |
| SS (Pin 6) | Soft-start timing node | Charged by 5-μA internal current; RC network (e.g., 1-μF + 200-kΩ) sets output ramp time; discharged via R3 on disable. |
| FB (Pin 7) | Output voltage feedback input | Senses divided output voltage; regulates to 0.5 V reference; determines output setpoint (e.g., 15 V = R1/R2 = 29:1). |
| OUT (Pin 8) | Isolated output connection | Load connects here for input-output isolation during shutdown; series path includes isolation FET (RDS(on) ≈ 4 Ω). |
| SW (Pin 9) | Internal switch node | Connects to inductor and diode; carries high dv/dt switching waveform; requires tight layout and Kelvin routing. |
| VO (Pin 10) | Boost converter output | Direct output of boost stage; bypasses isolation FET when load connected here - higher efficiency but no overload protection. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isolation FET | Enables true input-output disconnect during shutdown and overload - eliminates leakage paths and protects upstream supply. |
| Programmable soft start | RC network on SS pin controls output voltage ramp rate, reducing inrush current into large output capacitors (e.g., 100-μF). |
| Load discharge path | Internal diode network discharges OUT pin to <4.3 V within milliseconds of shutdown - prevents hazardous residual voltage. |
| Fixed 1.2-MHz operation | Eliminates external frequency-setting components; ensures consistent EMI profile and simplifies filter design. |
| Current-mode control w/ slope comp | Provides inherent cycle-by-cycle current limiting and stable loop response across wide input/output ranges without external compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610981DSER | Same WSON-10 package, 1.2-MHz frequency, but lacks isolation FET and load discharge; lower quiescent current (0.6 μA). | No input-output isolation or automatic load discharge - unsuitable where shutdown leakage or residual voltage must be eliminated. | Select when ultra-low IQ dominates requirements and isolation is unnecessary; verify external OVP/OC protection if needed. |
| MAX17222ETA+T | 2.5-V to 5.5-V input, 1.2-MHz, 0.5-V FB, but no isolation FET; max output 5.5 V; smaller 2 mm × 2 mm TDFN-8 package. | Limited to ≤5.5-V output - cannot replace TPS61093DSKT in 12–17-V applications; no isolation or discharge capability. | Choose only for low-voltage boost (≤5.5 V) where board space is critical and isolation is irrelevant. |
Compared with TPS61093DSKT, TPS610981DSER offers lower IQ but forfeits isolation and discharge functions, while MAX17222ETA+T supports only sub-6-V outputs and lacks both isolation and high-voltage capability - making TPS61093DSKT uniquely suited for 12–17-V isolated portable power.

FAQ
What is the maximum output voltage supported by the TPS61093DSKT?
The TPS61093DSKT supports up to 17 V at the VO pin, with overvoltage protection triggering at 19 V (typical). When configured for 15-V output - as validated in the datasheet's typical application - it delivers 50 mA with up to 88% efficiency. Output voltage is set via external resistor divider on the FB pin, referenced to 0.5 V.
How does the isolation FET in the TPS61093DSKT improve system safety?
The isolation FET in the TPS61093DSKT disconnects the OUT pin from VIN during shutdown and overload events, eliminating leakage paths and preventing backfeed into the input supply. This feature ensures <1 μA shutdown current and rapidly discharges the output capacitor to <4.3 V - critical for battery-powered medical devices like glucose meters where residual voltage poses safety or regulatory risks.
Can the TPS61093DSKT operate from a single Li-ion battery?
Yes, the TPS61093DSKT operates from 1.6 V to 6 V, fully covering the discharge range of a single Li-ion cell (typically 3.0 V to 4.2 V). Its 1.55-V undervoltage lockout prevents malfunction at end-of-discharge, and its high efficiency preserves runtime - e.g., delivering 15 V @ 50 mA from 3.6-V input with ~85% efficiency per datasheet curves.
What is the purpose of the CP1 and CP2 pins on the TPS61093DSKT?
The CP1 and CP2 pins on the TPS61093DSKT connect to an external 10-nF flying capacitor that enables the internal charge pump driving the gate of the isolation FET. This allows the FET to fully enhance using only the input supply - eliminating need for external high-side gate drivers or auxiliary supplies while maintaining reliable isolation switching across the full input range.
Does the TPS61093DSKT require external compensation components?
No, the TPS61093DSKT integrates internal slope compensation and error amplifier compensation optimized for standard external components (e.g., 4.7–10 μH inductors, 1–10 μF output caps). Stability is maintained across recommended operating conditions without external RC networks - though Figure 9 in the datasheet provides Bode plot data for custom designs using non-standard capacitors or inductors.
