Product details
Overview
TPS60110PWPR from Texas Instruments is a regulated 5-V ±4% step-up charge pump DC/DC converter for battery-powered systems, delivering up to 300 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 operates in push-pull topology for low-noise power delivery in portable instrumentation and medical devices.
For engineers reviewing the TPS60110PWPR datasheet, TPS60110PWPR pinout, TPS60110PWPR application, or TPS60110PWPR equivalent, key selection criteria include its dual-mode operation (pulse-skip for ultra-low quiescent current or constant-frequency for minimal ripple), thermally enhanced 20-pin TSSOP PowerPAD™ package, and integrated feedback reference enabling precise 5-V regulation without external resistors.
Technical Context
The TPS60110PWPR implements two synchronized, 180°-phase-shifted single-ended charge pumps operating in push-pull mode to sustain near-constant output current and achieve sub-10 mVpp ripple. Its internal 1.22 V bandgap reference and on-chip resistive divider set the 5 V output via FB pin connection to OUT.
Mode selection is hardware-configured: SKIP pin selects between constant-frequency (300 kHz typical) and pulse-skip operation; COM pin selects push-pull (low) or single-ended (high) topology; ENABLE enables shutdown with 0.05 µA supply current and load isolation. SYNC/CLK support external clock synchronization up to 800 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5 V ±4% - tightly regulated via internal 1.22 V reference and on-chip feedback divider; no external resistor network needed. |
| Max output current | 300 mA at 3 V input - sufficient for microprocessor core rails and USB-peripheral power in portable systems. |
| 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 without external supervision. |
| Output ripple | <10 mVpp at 300 mA - achieved in constant-frequency mode using X5R/X7R ceramic capacitors; enables noise-sensitive analog circuitry. |
| Quiescent current | 60 µA typical (no load, constant-frequency) - extends runtime in always-on battery backup applications. |
| Shutdown current | 0.05 µA max - isolates load from input and preserves battery life during system sleep states. |
| Switching frequency | 300 kHz typical (internal oscillator) - balances EMI, capacitor size, and efficiency; externally synchronizable up to 800 kHz. |
Pinout & Package
The TPS60110PWPR is housed in a thermally enhanced 20-pin TSSOP PowerPAD™ (PWP) package with an exposed thermal pad that must be soldered to PGND for effective heat dissipation and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1, 20) | Analog ground reference | Connects to internal bandgap and error amplifier; requires short trace to PGND plane for stable regulation. |
| ENABLE (3) | Logic-controlled enable | Active-high input; pulls device into 0.05 µA shutdown with load isolation when low. |
| FB (4) | Feedback sensing node | Internally referenced to 1.22 V; connect directly to OUT near load for optimal line/load regulation. |
| OUT (5, 16) | Regulated 5-V output | Dual pins reduce IR drop; must be tied together with short trace and bypassed with ≥33 µF ceramic CO. |
| C1+/C1− (6, 8), C2+/C2− (13, 15) | Flying capacitor terminals | Each pair connects one 2.2 µF X5R/X7R ceramic flying capacitor; phase-aligned for push-pull operation. |
| IN (7, 14) | Input power rail | Dual pins minimize input impedance; bypass with 15 µF ceramic CIN close to package. |
| PGND (9–12) | Power ground return | High-current path for charge-pump switching; must be solidly connected to thermal pad and ground plane. |
| SKIP (17) | Operating mode control | Low = constant-frequency (low ripple); high = pulse-skip (low IQ); must not float. |
| COM (18) | Topology selection | Low = push-pull (low ripple, dual flying caps); high = single-ended (board space saving, one 4.7 µF cap). |
| SYNC (2), CLK (19) | External clock interface | SYNC = IN + CLK = external signal enables synchronization up to 800 kHz; reduces EMI in noise-critical systems. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic components and associated EMI; simplifies layout and reduces BOM count to just four ceramic capacitors. |
| Push-pull charge-pump topology | Two 180°-phase-shifted pumps deliver continuous output current, achieving <10 mVpp ripple at full 300 mA load. |
| Dual-mode operation | Hardware-selectable: constant-frequency (300 kHz) for predictable noise spectrum or pulse-skip for 60 µA IQ at light loads. |
| Integrated feedback reference | On-chip 1.22 V bandgap and fixed-resistor divider enable precise 5 V ±4% regulation without external components. |
| Thermal PowerPAD™ package | 20-pin TSSOP with exposed copper pad; achieves 33°C/W θJA when soldered to PGND, supporting 3 W dissipation at 25°C ambient. |

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 max output current; same 5 V ±4% regulation, 2.7–5.4 V input, and PWP package. | Lower current capability limits use to low-power peripherals (e.g., sensors, RTCs) rather than microprocessor I/O rails. | Select when system load is ≤150 mA and board space or cost optimization is prioritized over headroom. |
| MAX862ESA+ | 5 V ±5% output; 250 mA max; SO-8 package; no push-pull topology or external clock sync. | Lacks dual-mode operation and thermal PowerPAD™, resulting in higher thermal resistance and less flexible ripple/noise tradeoff. | Choose only if legacy SO-8 footprint compatibility is mandatory and 300 mA output is not required. |
Compared with TPS60111PWPR and MAX862ESA+, the TPS60110PWPR uniquely delivers 300 mA output with sub-10 mVpp ripple in a thermally optimized package, making it the only option among the three capable of powering demanding mixed-signal SoCs in compact portable designs without inductors.

FAQ
What is the minimum input voltage required for TPS60110PWPR to start up and regulate 5 V?
The TPS60110PWPR starts regulation when input voltage reaches 2.7 V. During startup, it charges the output capacitor until VO reaches 0.8 × VIN; at 2.7 V input, this threshold is 2.16 V, well below the 5 V target, ensuring reliable turn-on even with deeply discharged batteries. Startup time is typically under 200 µs with a 16.5 Ω load.
Can TPS60110PWPR operate with ceramic capacitors only, and what dielectric types are recommended?
Yes, the TPS60110PWPR is explicitly designed for ceramic capacitors: X5R or X7R dielectrics are required for all external capacitors (CIN, C1F, C2F, CO). These offer low ESR and stable capacitance across temperature and bias, essential for achieving <10 mVpp ripple and maintaining regulation under load transients.
How does the TPS60110PWPR achieve load isolation during shutdown?
When ENABLE is pulled low, the TPS60110PWPR disables all internal switches-including those connecting IN to OUT-and places the output in high-impedance state. This results in ≤1 µA output leakage current, effectively isolating the load from the input source and preventing battery drain during system sleep or power-off states.
What is the purpose of the COM pin on the TPS60110PWPR, and how does it affect design?
The COM pin selects between push-pull (COM = low) and single-ended (COM = high) operation. Push-pull uses both flying capacitors in anti-phase for lowest ripple; single-ended ties C1F and C2F in parallel, reducing component count to one 4.7 µF capacitor but increasing ripple amplitude. Designers choose based on noise vs. board space tradeoffs.
Is an evaluation module available for the TPS60110PWPR, and what is its part number?
Yes, the TPS60110EVM−132 evaluation module is available for the TPS60110PWPR. It provides a fully assembled and tested platform with jumpers for mode selection (SKIP, COM), test points for all critical signals, and pre-optimized layout for thermal and EMI performance-enabling rapid validation of 5 V boost functionality in target applications.
