Product details
Overview
TPS60111PWP from Texas Instruments is a regulated 5-V ±4% step-up charge pump DC/DC converter for battery-powered systems, delivering up to 150 mA output current from 2.7–5.4 V input (e.g., single Li-ion or three alkaline cells), with <10 mVPP output ripple in constant-frequency mode and only four external ceramic capacitors required. It targets space-constrained portable instrumentation and medical devices requiring low EMI and no inductors.
For engineers reviewing the TPS60111PWP datasheet, TPS60111PWP pinout, TPS60111PWP application, or TPS60111PWP equivalent, key selection criteria include its dual-mode operation (pulse-skip vs. constant-frequency), push-pull charge-pump architecture for ripple suppression, thermal-enhanced 20-pin TSSOP PowerPAD™ package, and shutdown isolation with 0.05 µA quiescent current.
Technical Context
The TPS60111PWP implements two synchronized, 180°-phase-shifted single-ended charge pumps operating in push-pull mode when COM = low, enabling continuous output current transfer and minimizing voltage ripple. Its internal 300 kHz oscillator (or external sync up to 800 kHz) drives high-current MOSFET switches controlled by an error amplifier referencing a 1.22 V bandgap.
Regulation is achieved via feedback at the FB pin, where an on-chip resistive divider compares output voltage to the 1.22 V reference. Mode selection is hardware-configurable: SKIP pin selects pulse-skip (low IQ, variable ripple frequency) or constant-frequency (low ripple amplitude, fixed 300 kHz) operation; COM pin selects push-pull (low ripple) or single-ended (reduced component count) topology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% - tightly regulated rail for logic and analog circuitry without external feedback resistors. |
| Max Output Current | 150 mA at 3 V input - sufficient for microprocessor core rails or sensor signal chains in portable equipment. |
| Input Voltage Range | 2.7 V to 5.4 V - supports single Li-ion (2.7–4.2 V), LiFePO₄, or triple alkaline/NiMH batteries directly. |
| Output Ripple | <10 mVPP at 150 mA - achieved in constant-frequency mode with CO = 22 µF + 10 µF X5R ceramic, enabling noise-sensitive analog stages. |
| Quiescent Current | 60 µA typical (no load, constant-frequency) - extends battery life in always-on monitoring applications. |
| Shutdown Current | 0.05 µA max - isolates load from input during sleep, critical for multi-day battery runtime in handheld instruments. |
| Switching Frequency | 300 kHz internal (200–400 kHz range); externally synchronizable up to 800 kHz - allows EMI filtering and avoids sensitive IF bands. |
Pinout & Package
TPS60111PWP is housed in a thermally enhanced 20-pin HTSSOP PowerPAD™ (PWP) package with an exposed thermal pad on the bottom for PCB heat sinking. The package supports tape-and-reel ordering with R suffix (TPS60111PWPR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (7, 14) | Power input | Dual pins for low-impedance connection of 2.7–5.4 V supply; must be bypassed locally with ≥4.7 µF ceramic capacitor. |
| OUT (5, 16) | Regulated 5-V output | Dual pins for low-ESR output routing; connect together and bypass to PGND with ≥33 µF ceramic for low ripple. |
| PGND (9–12) | Power ground | Four dedicated pins carry high-frequency charge-pump return current; must be tied directly to thermal pad and power plane. |
| GND (1, 20) | Analog ground | Reference ground for internal bandgap and error amplifier; connect to PGND via short trace near IC. |
| FB (4) | Feedback input | Connects directly to OUT near load to compensate for IR drop; internal 1.22 V reference sets output voltage. |
| ENABLE (3) | Logic enable | Active-high control: pulls output high-impedance and reduces supply current to 0.05 µA when low. |
| SKIP (17) | Mode select | Low = constant-frequency (300 kHz, low ripple); high = pulse-skip (low IQ, variable frequency). |
| COM (18) | Topology select | Low = push-pull (two flying caps, low ripple); high = single-ended (one combined flying cap, minimal board area). |
| C1+/C1− (6, 8), C2+/C2− (15, 13) | Flying capacitor terminals | Four dedicated pins for two independent 1 µF ceramic flying capacitors; layout symmetry critical for ripple performance. |
| SYNC (2), CLK (19) | External clock interface | SYNC = IN enables external clock; CLK accepts up to 800 kHz signal - switching frequency = CLK/2. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI, simplifies layout, and reduces BOM cost - ideal for compact medical sensors and PDAs. |
| Push-pull charge-pump topology | Ensures continuous output current delivery and <10 mVPP ripple at full load without LC filtering. |
| Hardware-selectable operating modes | SKIP and COM pins allow real-time tradeoff between light-load efficiency (pulse-skip) and output noise (constant-frequency). |
| Thermal-enhanced PowerPAD™ package | RθJA = 178°C/W enables 448 mW dissipation at 70°C ambient - supports 150 mA output in confined enclosures. |
| Load isolation in shutdown | EN = low disconnects OUT from IN and limits output leakage to ≤1 µA - preserves backup battery charge in emergency systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60110PWP | Higher 300 mA output current; same 5-V ±4% regulation and pinout; requires larger flying/output capacitors. | Targets higher-power applications like laptop USB ports or motor drivers where >150 mA is needed. | Select TPS60110PWP only if sustained >150 mA load current is required; otherwise TPS60111PWP offers better light-load efficiency. |
| MAX680ESA+ | Unregulated 2× charge pump (VOUT ≈ 2×VIN); no feedback, no 5-V regulation; 100 mA max; 8-pin SOIC. | Suitable for non-critical digital rails where input voltage is stable and exact 5 V is not required. | Choose MAX680ESA+ only for cost-sensitive, low-precision applications; TPS60111PWP provides regulation, lower ripple, and higher current. |
Compared with TPS60110PWP and MAX680ESA+, the TPS60111PWP uniquely balances 150 mA output, ±4% regulation, <10 mVPP ripple, and 0.05 µA shutdown - making it optimal for precision portable instrumentation where size, noise, and battery life are co-constrained.

FAQ
What is the maximum output current capability of the TPS60111PWP?
The TPS60111PWP delivers up to 150 mA output current when supplied from a 3 V input, as specified in the SLVS216B datasheet. At higher input voltages (e.g., 5.4 V), the device maintains 150 mA but may require careful thermal design due to reduced power dissipation margin. Absolute maximum continuous output current is rated at 200 mA, though regulation and ripple specifications apply only up to 150 mA.
Does the TPS60111PWP require external feedback resistors to set the output voltage?
No, the TPS60111PWP does not require external feedback resistors. It features an internal resistive divider referenced to a 1.22 V bandgap, which sets the regulated output to 5 V ±4%. The FB pin connects directly to the OUT pin near the load to maintain regulation accuracy under varying load conditions and PCB trace resistance.
How does the TPS60111PWP achieve low output voltage ripple without inductors?
The TPS60111PWP achieves low output voltage ripple through a push-pull charge-pump architecture: two single-ended charge pumps operate 180° out of phase, ensuring continuous current transfer to the output capacitor. In constant-frequency mode (SKIP = low), this results in <10 mVPP ripple at 150 mA with proper ceramic capacitor selection (e.g., 22 µF + 10 µF X5R).
Can the TPS60111PWP be synchronized to an external clock signal?
Yes, the TPS60111PWP supports external clock synchronization. Connect SYNC to IN and drive CLK with a square wave up to 800 kHz; the internal switching frequency becomes half the CLK frequency. External sync is recommended only in constant-frequency mode to preserve predictable EMI profiles and avoid instability in pulse-skip operation.
What is the thermal performance of the TPS60111PWP in its PWP package?
The TPS60111PWP in the 20-pin HTSSOP PowerPAD™ (PWP) package has a junction-to-ambient thermal resistance (RθJA) of 178°C/W. At 25°C ambient, it supports 700 mW continuous dissipation; derating yields 448 mW at 70°C ambient. Proper soldering of the exposed thermal pad to a large PCB copper area is essential to achieve these ratings and sustain 150 mA output reliably.
