Product details
Overview
TPS60110PWPG4 from Texas Instruments is a regulated 5-V ±4% step-up charge pump DC/DC converter delivering up to 300 mA output current from a 2.7-V to 5.4-V input (e.g., single Li-ion or three alkaline/NiMH cells). It requires no inductors, achieves <10 mVPP output ripple in constant-frequency mode, and operates in thermally enhanced 20-pin TSSOP PowerPAD™ (PWP) package. It serves as a low-EMI power source for portable instrumentation and battery-powered microprocessor systems.
For engineers reviewing the TPS60110PWPG4 datasheet, TPS60110PWPG4 pinout, TPS60110PWPG4 application, or TPS60110PWPG4 equivalent, key selection criteria include its dual-mode operation (pulse-skip vs. constant-frequency), push-pull charge-pump architecture for ripple reduction, 60-µA quiescent current, shutdown isolation, and compatibility with ceramic flying capacitors.
Technical Context
The TPS60110PWPG4 implements two synchronized, 180° out-of-phase single-ended charge pumps controlled by an internal 300-kHz oscillator (or external clock up to 800 kHz), enabling continuous output current delivery and minimizing voltage ripple. Its regulation loop uses a 1.22-V internal reference and on-chip resistive divider, with feedback (FB) connected directly to the output for precise 5-V ±4% regulation across load and line variations.
Mode selection is hardware-configured: SKIP pin selects between pulse-skip (low IQ, variable-frequency) and constant-frequency (low ripple, fixed 300 kHz) operation; COM pin selects push-pull (low ripple, two flying caps) or single-ended (board-space optimized, one combined cap) topology. ENABLE provides logic-controlled shutdown with 0.05-µA supply current and load isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% - tightly regulated rail for USB-peripheral or microcontroller I/O domains without external feedback resistors. |
| Max Output Current | 300 mA at 3-V input - sufficient to power ARM Cortex-M microcontrollers, LCD bias circuits, or sensor signal chains. |
| Input Voltage Range | 2.7 V to 5.4 V - supports single-cell Li-ion (2.7–4.2 V), LiFePO₄, or triple-alkaline/NiMH batteries without pre-regulation. |
| Output Ripple | <10 mVPP in constant-frequency mode - enables noise-sensitive analog circuitry (e.g., ADC references) without LC filtering. |
| Quiescent Current | 60 µA typical - extends battery life in always-on monitoring applications such as medical wearables or IoT edge nodes. |
| Shutdown Current | 0.05 µA max - ensures negligible drain during system sleep, critical for multi-year battery deployments. |
| Switching Frequency | 300 kHz internal / up to 800 kHz external - allows EMI filtering design with predictable spectral content and avoids AM radio band interference. |
Pinout & Package
The TPS60110PWPG4 is housed in a 20-pin TSSOP PowerPAD™ (PWP) package with exposed thermal pad soldered to PGND for enhanced thermal performance. The PowerPAD must be electrically and thermally connected to PCB ground plane via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1, 20) | Analog ground reference | Provides low-noise return path for internal bandgap and error amplifier; must be short-traced to PGND. |
| IN (7, 14) | Power input | Dual-input pins reduce trace inductance; bypassed with ≥15 µF ceramic capacitor close to device. |
| OUT (5, 16) | Regulated 5-V output | Dual-output pins lower impedance; connect both with short traces and bypass with ≥33 µF CO capacitor. |
| PGND (9–12) | Power ground | Carries high-frequency switching current; must be solidly tied to PowerPAD and separated from analog GND until star point. |
| ENABLE (3) | Logic enable control | Active-high input; pulls output to high-Z and reduces supply current to 0.05 µA when low. |
| FB (4) | Feedback sense | Connects directly to OUT near load to compensate for IR drop; internal 1.22-V reference sets 5-V output. |
| SKIP (17) | Operating mode select | Low = constant-frequency (low ripple); high = pulse-skip (low IQ); determines tradeoff between efficiency and noise. |
| COM (18) | Topology select | Low = push-pull (two flying caps, low ripple); high = single-ended (one combined cap, minimal board area). |
| C1+/C1−, C2+/C2− (6,8,15,13) | Flying capacitor terminals | Each pair connects to dedicated 2.2-µF ceramic flying capacitor; polarity must match schematic. |
| SYNC (2), CLK (19) | External clock interface | SYNC = IN + CLK = external signal enables synchronization to system clock; disables internal oscillator. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI, simplifies layout, and avoids inductor saturation issues in space-constrained portable designs. |
| Push-pull charge-pump topology | Delivers near-constant output current by interleaving two charge phases, reducing output ripple by >50% vs. single-ended mode. |
| Hardware-selectable operating modes | SKIP and COM pins allow real-time optimization of efficiency (pulse-skip) or noise (constant-frequency) without firmware changes. |
| Integrated load isolation in shutdown | Prevents backfeed from output to input during battery swap or system reset, protecting upstream power sources and downstream loads. |
| Thermally enhanced PowerPAD™ package | 33°C/W junction-to-ambient thermal resistance (with vias) enables 300-mA operation at 70°C ambient without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60111PWPR | 150-mA output current, same 5-V ±4% regulation, identical PWP package and pinout. | Lower output capability suits lower-power peripherals (e.g., Bluetooth LE sensors) but cannot replace TPS60110PWPG4 in 300-mA loads. | Select only if system peak current ≤150 mA and footprint compatibility is required. |
| MAX862ESA+ | 5-V ±4% output, 250-mA max, SO-8 package, no COM/SKIP mode flexibility, higher 120-µA IQ. | Lacks push-pull topology and dual-mode control; less suitable for ultra-low-ripple or ultra-low-IQ requirements. | Consider for cost-sensitive, space-tolerant designs where 250-mA output and fixed operation suffice. |
Compared with TPS60111PWPR and MAX862ESA+, the TPS60110PWPG4 uniquely delivers 300-mA output with hardware-selectable ripple/efficiency tradeoffs and integrated load isolation-making it optimal for portable instrumentation demanding both high current and low-noise operation.

FAQ
What is the maximum output current capability of the TPS60110PWPG4?
The TPS60110PWPG4 delivers up to 300 mA output current when supplied from a 3-V input, as specified in the electrical characteristics table. At higher input voltages (e.g., 5.4 V), output current remains limited by internal current protection and thermal constraints-not just voltage headroom. Derating applies above 70°C ambient due to the PWP package's 33°C/W thermal resistance.
How does the TPS60110PWPG4 achieve low output voltage ripple without inductors?
The TPS60110PWPG4 uses a push-pull dual charge-pump architecture where two flying capacitors operate 180° out of phase. This interleaved operation ensures near-continuous current delivery to the output capacitor, reducing ripple amplitude to <10 mVPP in constant-frequency mode-without requiring magnetic components or complex compensation networks.
Can the TPS60110PWPG4 be synchronized to an external clock?
Yes-the TPS60110PWPG4 supports external clock synchronization: tie SYNC to IN and drive CLK with a square wave up to 800 kHz. The internal switching frequency becomes half the external clock frequency. Synchronization is recommended in constant-frequency mode to maintain predictable EMI spectra and avoid beat frequencies in multi-rail systems.
What happens to the output load during TPS60110PWPG4 shutdown?
When ENABLE is driven low, the TPS60110PWPG4 disconnects the output from the input via internal switches, placing the load in high-impedance state. Output leakage current is ≤1 µA, and supply current drops to 0.05 µA max-ensuring zero backfeed and safe hot-swap capability for battery replacement or system-level power sequencing.
Which external capacitors are mandatory for basic TPS60110PWPG4 operation?
Four external capacitors are mandatory: one 15-µF input capacitor (CIN), two 2.2-µF ceramic flying capacitors (C1F, C2F), and one 33-µF output filter capacitor (CO). Ceramic X5R/X7R dielectrics are required for all; tantalum alternatives are permitted for CIN/CO but increase ripple and size. No resistors or inductors are needed for baseline operation.
