Product details
Overview
TPS60101PWPRG4 from Texas Instruments is a regulated step-up charge pump DC/DC converter generating 3.3 V ±4% from 1.8–3.6 V input (e.g., two alkaline/NiMH cells), delivering up to 100 mA output current with <5 mVPP ripple, 90% efficiency, and 50 µA quiescent current. It replaces inductor-based converters in space-constrained battery-powered microprocessor systems.
For engineers reviewing the TPS60101PWPRG4 datasheet, TPS60101PWPRG4 pinout, TPS60101PWPRG4 application, or TPS60101PWPRG4 equivalent, key selection criteria include regulated 3.3-V output tolerance, push-pull vs. pulse-skip mode tradeoffs, thermal performance in the 20-pin TSSOP PowerPAD™ package, and external capacitor count (only four required).
Technical Context
The TPS60101PWPRG4 implements a dual single-ended charge pump architecture operating in 180° phase-shifted push-pull mode to sustain near-constant output current and minimize ripple. Its internal 300 kHz oscillator drives high-current MOSFET switches controlled by an error amplifier referencing a 1.22 V bandgap.
Mode selection is fully configurable via three logic inputs: SKIP selects constant-frequency (low-noise) or pulse-skip (low-IQ) operation; COM selects push-pull (low-ripple) or single-ended (reduced capacitor count) topology; 3V8 selects regulated 3.3 V or preregulated 3.8 V output voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (regulated); selectable 3.8 V preregulated mode via 3V8 pin |
| Input Voltage Range | 1.8 V to 3.6 V - supports two-cell alkaline/NiCd/NiMH batteries without under-voltage risk |
| Max Output Current | 100 mA at 2 V input - sufficient for low-power microcontrollers and sensors |
| Output Ripple | <5 mVPP in constant-frequency mode with 22 µF X5R ceramic CO - enables noise-sensitive analog circuits |
| Quiescent Current | 50 µA typical - extends battery life in always-on portable instrumentation |
| Shutdown Current | 0.05 µA - isolates load and preserves battery during system sleep |
| Switching Frequency | 300 kHz internal (200–400 kHz range); externally synchronizable up to 800 kHz - allows EMI control in dense layouts |
Pinout & Package
The TPS60101PWPRG4 is housed in a thermally enhanced 20-pin TSSOP PowerPAD™ (PWP) package with an exposed thermal pad on the bottom for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1,20) | Analog ground reference | Connects to PGND via short trace; provides stable reference for internal 1.22 V bandgap and error amplifier |
| IN (7,14) | Power input | Dual pins for low-impedance connection of 1.8–3.6 V supply; bypass with ≥4.7 µF 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 return | Carries high-frequency charge-pump switching current; must be tied directly to thermal pad and input/output caps |
| ENABLE (3) | Logic-controlled shutdown | Active-high enable; pulls output high-Z and reduces IQ to 0.05 µA when low |
| FB (4) | Feedback input | Internally connected to resistive divider; connect directly to OUT near load for tight regulation |
| SKIP (17) | Operating mode select | Low = constant-frequency (low ripple); high = pulse-skip (low IQ) |
| 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 LDO post-regulation |
| C1+/C1−, C2+/C2− (6,8,15,13) | Flying capacitor terminals | Four dedicated pins for two 1 µF ceramic flying capacitors - no inductors required |
| SYNC (2) | External clock input | Connect to GND for internal clock; connect to IN to accept external 400–800 kHz signal (output switches at half frequency) |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI and board area occupied by inductors; uses only four ceramic capacitors |
| Configurable dual-mode operation | Independent selection of regulation mode (3.3 V/3.8 V), topology (push-pull/single-ended), and control scheme (constant-frequency/pulse-skip) |
| Thermally optimized package | TSSOP PowerPAD™ with exposed thermal pad achieves 178°C/W θJA; supports 700 mW dissipation at 25°C ambient |
| Load isolation in shutdown | EN = low disconnects output from input and reduces leakage to ≤1 µA - prevents battery drain in standby |
| Undervoltage lockout | Deactivates device below 1.6 V input - protects battery from deep discharge and ensures clean startup |

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 fixed 3.3 V output (no 3.8 V mode) and no SYNC input | Lacks external clock synchronization and preregulated 3.8 V option - suitable only for basic 3.3 V applications | Select when external clock sync or LDO pre-regulation is unnecessary and BOM simplification is prioritized |
| MAX680ESA+ | 8-pin SOIC, 50 mA max output, fixed 5 V output, no mode-select pins, higher 125 µA IQ | Lower current capability and no programmability - limited to low-power 5 V legacy designs | Select only for drop-in replacement in existing 5 V systems where footprint and feature set match legacy layout |
Compared with TPS60101PWPRG4, TPS60110PWPR offers identical packaging and core functionality but omits 3.8 V mode and SYNC, reducing flexibility; MAX680ESA+ provides simpler integration in 5 V systems but sacrifices current capability, programmability, and ultra-low quiescent current essential for modern portable devices.

FAQ
What input voltage range does the TPS60101PWPRG4 support, and what battery configurations does it target?
The TPS60101PWPRG4 supports a 1.8 V to 3.6 V input voltage range, optimized for two-cell alkaline, NiCd, or NiMH battery stacks. Its undervoltage lockout activates at 1.6 V to prevent deep discharge. This makes TPS60101PWPRG4 ideal for portable instruments where battery voltage decays from ~3.2 V (fresh) to ~2.0 V (end-of-life), maintaining regulated 3.3 V output throughout.
How does the TPS60101PWPRG4 achieve low output voltage ripple without inductors?
The TPS60101PWPRG4 uses a dual single-ended charge pump operating in push-pull mode with 180° phase shift. While one flying capacitor charges from input, the other transfers stored charge to the output - ensuring continuous current delivery. With proper 22 µF X5R ceramic output capacitance and constant-frequency mode (SKIP = low), TPS60101PWPRG4 achieves <5 mVPP ripple, eliminating need for EMI-prone inductors.
Can the TPS60101PWPRG4 generate voltages other than 3.3 V?
Yes - the TPS60101PWPRG4 supports a second output mode: when the 3V8 pin is driven high (to IN), it generates a preregulated 3.8 V output (3.6–4.0 V range) from 2.2–3.6 V input. This mode is intended for feeding low-dropout regulators (LDOs) where tighter final output tolerance is required. The TPS60101PWPRG4 does not support arbitrary output voltages - only these two factory-trimmed options.
What is the role of the COM pin on the TPS60101PWPRG4, and how does it affect design?
The COM pin selects between push-pull (COM = low) and single-ended (COM = high) charge pump topology. In push-pull mode, both flying capacitors operate 180° out of phase, minimizing output ripple and enabling full 100 mA output. In single-ended mode, both pumps operate in parallel using one effective flying capacitor (C1F + C2F), reducing component count but increasing ripple. Designers choose COM based on ripple vs. board space tradeoff - TPS60101PWPRG4 requires explicit COM configuration for either behavior.
Does the TPS60101PWPRG4 require external components beyond capacitors, and what are the minimum requirements?
No - the TPS60101PWPRG4 requires only four external ceramic capacitors: one input (CIN ≥ 4.7 µF), two flying (C1F/C2F = 1 µF each), and one output (CO = 10–22 µF depending on mode). No resistors, diodes, or inductors are needed. Feedback is internal (1.22 V reference with on-chip divider), and all mode control is via logic pins. This minimal BOM reduces cost, board area, and qualification effort - a key advantage of TPS60101PWPRG4 over traditional inductor-based converters.
