Product details
Overview
TPS60100PWPRG4 from Texas Instruments is a regulated step-up charge pump DC/DC converter delivering 3.3 V ±4% (or 3.8 V preregulated) from 1.8–3.6 V input, supporting up to 200 mA output current with <5 mVPP ripple in constant-frequency mode, used in battery-powered microprocessor systems and portable instrumentation.
For engineers reviewing the TPS60100PWPRG4 datasheet, TPS60100PWPRG4 pinout, TPS60100PWPRG4 application, or TPS60100PWPRG4 equivalent, key selection criteria include input voltage range (1.8–3.6 V), dual-mode operation (pulse-skip vs. constant-frequency), push-pull topology for low ripple, thermal performance in PWP package, and compatibility with ceramic flying capacitors.
Technical Context
The TPS60100PWPRG4 implements a dual single-ended charge pump architecture operating in 180° phase-shifted push-pull mode to maintain near-constant output current and minimize ripple. It integrates a 1.22 V bandgap reference, error amplifier, and MOSFET switch control circuitry with internal resistive feedback.
Mode selection is fully configurable via three logic inputs: SKIP selects pulse-skip (low quiescent current) or constant-frequency (low ripple) operation; COM enables push-pull (low ripple) or single-ended (reduced capacitor count) topology; 3V8 configures regulated 3.3 V or preregulated 3.8 V output. Internal switching frequency is 300 kHz (±100 kHz), adjustable to 400–800 kHz via external SYNC clock.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (3.17–3.43 V) or 3.8 V ±5.3% (3.6–4.0 V); supports dual regulation modes for LDO pre-regulation or direct 3.3 V rail generation. |
| Input Voltage Range | 1.8–3.6 V (3.3 V mode); 2.2–3.6 V (3.8 V mode); matches two-cell alkaline/NiMH/NiCd battery stacks without linear dropout loss. |
| Max Output Current | 200 mA at 2 V input; sufficient for low-power microcontrollers, sensors, and RF modules in portable devices. |
| Output Ripple | <5 mVPP at 200 mA in constant-frequency mode with 22 µF X5R ceramic CO; enables noise-sensitive analog and mixed-signal circuits. |
| Quiescent Current | 50 µA typical (no load, constant-frequency); 1.5 mA typical (no load, pulse-skip); extends battery life in intermittent-operation systems. |
| Shutdown Current | 0.05 µA max; isolates load from input during shutdown, critical for zero-leakage backup power paths. |
| Switching Frequency | 300 kHz internal (200–400 kHz range); externally synchronizable up to 800 kHz via SYNC pin for EMI control in dense layouts. |
Pinout & Package
TPS60100PWPRG4 uses the thermally enhanced 20-pin TSSOP PowerPAD™ (PWP) package with exposed thermal pad on bottom for improved heat dissipation. Pin numbering follows standard top-view layout with dual IN/OUT/PGND pins for low-impedance routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1, 20) | Analog ground reference | Connects to PGND through short trace; separates sensitive reference/control circuitry from high-current return paths. |
| IN (7, 14) | Power input | Dual-input pins reduce trace inductance; requires 10 µF ceramic bypass to GND near package edge. |
| OUT (5, 16) | Regulated output | Dual-output pins lower impedance; connect both to CO (22 µF X5R) and load with minimal loop area. |
| PGND (9–12) | Power ground return | Four dedicated pins carry charge-pump switching current; must be tied together and connected to thermal pad. |
| ENABLE (3) | Logic-controlled enable | Active-high; pulls supply current to 0.05 µA when low and disconnects load from input for true isolation. |
| FB (4) | Feedback input | Internally referenced to 1.22 V; connect directly to OUT near load for optimal regulation accuracy. |
| SKIP (17) | 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 (low ripple, two flying caps); high = single-ended (one flying cap, higher ripple). |
| 3V8 (19) | Output voltage select | Low = 3.3 V regulated; high = 3.8 V preregulated; enables cascaded LDO architectures for tighter tolerance. |
| SYNC (2) | External clock input | Connect to GND for internal clock; connect to IN for external sync (400–800 kHz) to align switching with system timing. |
| C1+/C1− (6,8), C2+/C2− (15,13) | Flying capacitor terminals | Each pair connects to 2.2 µF X5R/X7R ceramic; polarity must match schematic to avoid reverse bias damage. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI sources and board space for inductors; reduces BOM count to only four ceramic capacitors. |
| Push-pull charge pump topology | Ensures continuous output current delivery and <5 mVPP ripple at full load-critical for ADC references and RF front-ends. |
| Configurable operating modes | Three independent logic inputs (SKIP/COM/3V8) allow hardware-selectable optimization for efficiency, ripple, or output voltage. |
| Thermally enhanced PWP package | PowerPAD™ thermal pad enables 700 mW dissipation at 25°C ambient; RθJC = 3.5°C/W with infinite heatsink coupling. |
| Load isolation in shutdown | Output becomes high-impedance with <1 µA leakage when ENABLE = low-prevents battery drain in standby systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar charge pump DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60110PWPR | Same PWP package, identical pinout, but supports 1.5–3.6 V input and 250 mA output; includes soft-start and improved line regulation. | Higher output current and wider input range suit more demanding portable instruments with variable battery chemistries. | Select TPS60110PWPR when >200 mA load or <1.8 V brownout margin is required; otherwise TPS60100PWPRG4 offers cost-optimized fit. |
| MAX680ESA+ | 8-pin SOIC, fixed 5 V output, 100 mA max, no mode selection; uses single flying capacitor and lacks shutdown isolation. | Limited to fixed 5 V rails and lower current; suitable only for legacy designs where footprint and feature set are secondary. | Choose MAX680ESA+ only for space-constrained 5 V applications with no need for 3.3 V regulation or load isolation. |
Compared with TPS60100PWPRG4, TPS60110PWPR provides higher current headroom and broader input support for evolving battery technologies, while MAX680ESA+ trades configurability and isolation for minimal footprint in fixed-voltage legacy systems.

FAQ
What is the maximum output current capability of the TPS60100PWPRG4?
The TPS60100PWPRG4 delivers up to 200 mA output current when supplied from a 2 V input. At higher input voltages (e.g., 2.4–3.6 V), it maintains this rating across the full 3.3 V output range. The absolute maximum continuous output current is 300 mA, but sustained operation above 200 mA may exceed thermal limits in the PWP package without adequate PCB copper pour.
How does the TPS60100PWPRG4 achieve low output voltage ripple without an inductor?
The TPS60100PWPRG4 achieves <5 mVPP ripple using a dual single-ended charge pump in push-pull configuration: one pump charges its flying capacitor while the other transfers charge to the output capacitor, ensuring near-continuous current delivery. This topology eliminates inductor-induced ringing and EMI while enabling ceramic-only filtering.
Can the TPS60100PWPRG4 operate from a single 1.5 V alkaline cell?
No-the TPS60100PWPRG4 requires a minimum 1.8 V input for 3.3 V mode and 2.2 V for 3.8 V mode. A single 1.5 V alkaline cell falls below the undervoltage lockout threshold (1.6 V), preventing startup. Two alkaline cells (2.0–3.2 V fresh) or two NiMH cells (2.4–2.8 V) are the intended source.
What is the purpose of the COM pin on the TPS60100PWPRG4?
The COM pin selects between push-pull (COM = low) and single-ended (COM = high) charge pump operation. In push-pull mode, the two internal pumps operate 180° out-of-phase to minimize output ripple and maximize efficiency. In single-ended mode, both pumps operate in parallel, reducing required flying capacitance by half at the expense of higher ripple.
Does the TPS60100PWPRG4 require external compensation components?
No-the TPS60100PWPRG4 features internal compensation and a fixed 1.22 V reference with on-chip resistive feedback divider. The FB pin connects directly to the OUT pin near the load; no external resistors, capacitors, or compensation networks are needed for stable regulation across all operating conditions.
