Product details
Overview
TPS60101PWPR from Texas Instruments is a regulated step-up charge pump DC/DC converter delivering 3.3 V ±4% output from 1.8–3.6 V input, supporting up to 100 mA load current with <5 mVPP ripple in constant-frequency mode, no inductors required, and housed in a thermally enhanced 20-pin TSSOP PowerPAD™ package. It serves as a low-EMI power source for dual-cell battery systems powering microprocessors and portable instrumentation.
For engineers reviewing the TPS60101PWPR datasheet, TPS60101PWPR pinout, TPS60101PWPR application, or TPS60101PWPR equivalent, key selection criteria include its dual-mode operation (pulse-skip vs. constant-frequency), push-pull charge-pump topology for ripple suppression, 0.05 µA shutdown current, 300 kHz internal switching frequency, and configurable 3.3 V / 3.8 V output via 3V8 pin.
Technical Context
The TPS60101PWPR implements a dual single-ended charge-pump architecture operating in 180° phase-shifted push-pull mode to sustain near-continuous output current and minimize voltage ripple. Its regulation loop uses an internal 1.22 V reference and on-chip resistive divider tied to the FB pin, enabling precise 3.3 V output without external feedback components.
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 sets regulated 3.3 V or preregulated 3.8 V output. All modes maintain load isolation during shutdown.
Key Specifications

Pinout & Package
TPS60101PWPR is packaged in a 20-pin TSSOP PowerPAD™ (PWP) with exposed thermal pad for enhanced heat dissipation. The package measures 6.5 mm × 4.4 mm × 1.2 mm and supports tape-and-reel handling (R suffix denotes reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1, 20) | Analog ground reference | Connects to PGND via short trace; provides stable reference for internal bandgap and error amplifier |
| IN (7, 14) | Power input | Dual pins for low-impedance connection to 1.8–3.6 V source; requires local 4.7 µF bypass capacitor |
| OUT (5, 16) | Regulated output | Dual pins for low-ESR connection to 22 µF output capacitor; delivers 3.3 V or 3.8 V depending on 3V8 state |
| PGND (9–12) | Power ground | Carries high-frequency charge-pump switching current; must be connected directly to thermal pad and input/output caps |
| ENABLE (3) | Logic-controlled enable | Active-high; pulls supply current to 0.05 µA and disconnects load when low; requires valid VIN before assertion |
| FB (4) | Feedback input | Internally referenced to 1.22 V; connect directly to OUT near load for optimal regulation accuracy |
| SKIP (17) | Operating mode select | Low = constant-frequency (low ripple); high = pulse-skip (low IQ); determines tradeoff between noise and light-load efficiency |
| 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 output; high = 3.8 V preregulated output; enables cascaded LDO use |
| C1+/C1− (6, 8) C2+/C2− (15, 13) | Flying capacitor terminals | Four dedicated pins for two independent 1 µF ceramic flying capacitors; critical for charge transfer timing and ripple control |
| SYNC (2) | External clock input | Connect to GND for internal oscillator; connect to IN for external sync (max 800 kHz); requires 3V8-driven clock in sync mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What input voltage range does the TPS60101PWPR support, and how does it handle brownout conditions?
The TPS60101PWPR supports an input voltage range of 1.8 V to 3.6 V and incorporates an undervoltage lockout (UVLO) feature that disables the device when VIN drops below 1.6 V. This prevents erratic operation during battery depletion. During normal operation, the TPS60101PWPR maintains regulated 3.3 V output across the full 1.8–3.6 V range, with line regulation of 0.6%/V. The UVLO threshold has hysteresis to avoid oscillation near the trip point, ensuring clean shutdown and restart behavior.
How does the TPS60101PWPR achieve low output voltage ripple without inductors?
The TPS60101PWPR achieves low output voltage ripple (<5 mVPP) through its dual single-ended charge-pump architecture operating in push-pull mode with 180° phase shift. While one pump charges its flying capacitor (C1F), the other transfers stored charge to the output capacitor (CO), resulting in near-continuous current delivery. This topology, combined with internal 300 kHz switching and optimized ceramic capacitor selection (e.g., 22 µF X5R CO), suppresses ripple far beyond conventional single-pump designs-all without inductors or associated EMI concerns.
Can the TPS60101PWPR generate both 3.3 V and 3.8 V outputs, and what is the functional impact of each mode?
Yes, the TPS60101PWPR can generate either 3.3 V (regulated mode) or 3.8 V (preregulated mode) outputs, selected via the 3V8 pin. In 3.3 V mode (3V8 = low), the device regulates tightly to ±4% across load and input variations-ideal for direct powering of 3.3 V logic. In 3.8 V mode (3V8 = high), it delivers a less-tightly-regulated 3.6–4.0 V output optimized to feed a downstream LDO, enabling superior overall system accuracy and PSRR. Both modes retain full 100 mA capability and identical pin configuration.
What are the key differences between pulse-skip mode and constant-frequency mode on the TPS60101PWPR?
Pulse-skip mode (SKIP = high) halts switching when output voltage exceeds regulation threshold, reducing quiescent current to 50 µA and maximizing light-load efficiency-ideal for intermittent sensor wake-ups. Constant-frequency mode (SKIP = low) runs continuously at ~300 kHz, minimizing output ripple to <5 mVPP and enabling predictable EMI filtering-preferred for noise-sensitive analog or RF sections. Both modes retain full 100 mA capability and identical thermal performance under load.
Does the TPS60101PWPR provide load isolation during shutdown, and how is this implemented?
Yes, the TPS60101PWPR provides true load isolation during shutdown: when ENABLE is pulled low, all internal switches (including pass elements between IN and OUT) are turned off, disconnecting the output from the input. This results in <1 µA output leakage current and prevents backfeed into the battery source. The isolation is hardware-enforced and does not rely on external MOSFETs or diodes-ensuring zero standby drain in battery-backed memory, RTC, or security modules powered by the TPS60101PWPR.
