Product details
Overview
TPS60501DGS from Texas Instruments is a fixed-output 3.3-V, high-efficiency step-down charge pump DC-DC converter designed for space-constrained battery-powered systems. It delivers up to 250 mA output current with ≤3% voltage tolerance over line, load, and temperature, operates from 1.8 V to 6.5 V input, and integrates power-good supervision and thermal/overcurrent protection.
For engineers reviewing the TPS60501DGS datasheet, TPS60501DGS pinout, TPS60501DGS application, or TPS60501DGS equivalent, this page provides verified technical context, real-world conversion mode behavior, confirmed capacitor requirements (CIN = 4.7 µF, C1F/C2F = 1 µF, COUT ≥10 µF), and validated alternative options for low-noise, low-quiescent-current portable power rails.
Technical Context
The TPS60501DGS uses switched-capacitor fractional conversion - not inductive switching - to achieve up to 90% efficiency across wide input/output ratios. Its internal logic automatically selects among LDO, 2/3x, 0.5x, and 1/3x modes based on VIN/VOUT ratio and load, enabling stable regulation without inductors.
It features an integrated error amplifier, 800-kHz oscillator, bandgap reference, and open-drain PG output that asserts high when OUT reaches ≥97% of 3.3 V. Shutdown isolates load from battery, drawing only 0.05 µA, while soft-start limits inrush to 300 mA typical during startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±3% - guaranteed regulation across −40°C to +125°C, 0–150 mA load, and 4.3–6.5 V input range. |
| Max Output Current | 250 mA - achievable at VIN > VOUT + 1.2 V (i.e., VIN > 4.5 V); limited to 150 mA in skip-mode below that threshold. |
| Input Voltage Range | 1.8 V to 6.5 V - supports single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.4–3.2 V), and USB 5 V inputs. |
| Quiescent Current | <40 µA - enables multi-year battery life in always-on portable instrumentation and IoT edge sensors. |
| Efficiency | Up to 90% - measured at 150 mA, VIN = 5 V; maintains >75% efficiency down to 10 mA load due to adaptive mode switching. |
| Switching Frequency | 600–1200 kHz - fixed-frequency operation enables predictable EMI filtering; typical 800 kHz simplifies ceramic capacitor selection. |
| Power-Good Threshold | 97% of nominal (3.201 V) - open-drain PG pin pulls high only after regulated output stabilizes, enabling safe system sequencing. |
Pinout & Package
TPS60501DGS is housed in a 10-pin VSSOP package (3.05 mm × 4.98 mm), optimized for compact PCB layouts in handheld devices. Thermal resistance RθJA = 157°C/W ensures adequate self-heating control under 250-mA load at ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-low logic control: tie to GND to enable; pull high to disable and isolate load from input (ISHDN = 0.05 µA). |
| PG (Pin 2) | Power-good output | Open-drain signal indicating regulated output; requires external pull-up to VIN or OUT; asserts high at ≥3.201 V. |
| C2F− (Pin 3) | Flying capacitor terminal | Negative node of second flying capacitor (C2F); connects to internal switch matrix for 2/3x and 0.5x charge transfer phases. |
| C2F+ (Pin 4) | Flying capacitor terminal | Positive node of C2F; used in parallel-series reconfiguration during 0.5x and 1/3x conversion cycles. |
| VIN (Pin 5) | Main supply input | Accepts 1.8–6.5 V; requires 4.7-µF ceramic input capacitor to suppress ripple and sustain peak current during mode transitions. |
| C1F+ (Pin 6) | Flying capacitor terminal | Positive node of first flying capacitor (C1F); forms dual-capacitor charge pump network with C2F for fractional voltage reduction. |
| OUT (Pin 7) | Regulated output | 3.3-V power rail; bypassed with ≥10-µF ceramic capacitor (Co) to maintain stability and limit ripple to ≤30 mVPP at 150 mA. |
| C1F− (Pin 8) | Flying capacitor terminal | Negative node of C1F; switches between ground and OUT during alternating charge/discharge phases per oscillator cycle. |
| GND (Pin 9) | Ground reference | Common return for all internal circuits; must be low-impedance connection to minimize noise coupling into FB and PG paths. |
| FB (Pin 10) | Feedback input | Internally tied to OUT for fixed 3.3-V version; no external divider required - simplifies layout and eliminates resistor tolerance errors. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Eliminates magnetic components - reduces board area by >40% vs buck converters and avoids EMI from inductor ringing. |
| Adaptive conversion modes | Automatically selects LDO, 2/3x, 0.5x, or 1/3x mode to maximize efficiency across VIN/VOUT ratios - no firmware or external configuration needed. |
| Battery-shutdown isolation | When EN = high, load is fully disconnected from VIN; leakage from OUT to GND is <1 µA - preserves shelf life of coin-cell or Li-ion backup supplies. |
| Integrated power-good monitor | PG pin provides deterministic sequencing signal with 100–200 µs delay on ramp-up and 50–100 µs delay on ramp-down - enables reliable FPGA or MCU reset timing. |
| Robust protection suite | Thermal shutdown activates at 150°C; short-circuit current limit holds output at 300 mA typical until fault clears - prevents damage during hot-plug or capacitive load surges. |
Applications
| Mobile Phone Baseband Power | USB-Powered Peripheral Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60502DGS | Fixed 1.8-V output; minimum input 2.8 V; same pinout, package, and feature set. | Targets core logic rails (e.g., MCU cores, low-voltage sensors) instead of 3.3-V I/O interfaces. | Select when system requires 1.8 V instead of 3.3 V - no layout change needed, but FB pin is internally connected to OUT (no divider required). |
| MAX881RASA+ | Fixed 3.3-V output; 200-mA max; 1.6–6.5 V input; requires only three external caps; no PG output. | Lacks power-good signaling and thermal protection; lower max current limits use cases with sustained >200 mA loads. | Choose for cost-sensitive, non-safety-critical applications where PG sequencing and 250-mA headroom are unnecessary. |
Compared with TPS60501DGS, TPS60502DGS offers identical form-factor and protection but targets lower-voltage domains, while MAX881RASA+ trades PG functionality and current capability for reduced BOM count - making TPS60501DGS optimal for 3.3-V I/O rails demanding reliability and sequencing control.

FAQ
What is the minimum input voltage required for TPS60501DGS to deliver 150 mA?
The TPS60501DGS requires VIN > 4.3 V to sustain 150 mA output current, as specified in the device comparison table. Below this threshold, output current capability drops progressively - e.g., at VIN = 4.0 V, max IOUT is ~100 mA. This reflects the 2/3x and 0.5x mode activation boundaries inherent to its charge-pump architecture.
Does TPS60501DGS require external feedback resistors?
No. The TPS60501DGS has an internal resistor divider configured for fixed 3.3-V output; the FB pin must be connected directly to the OUT pin. External resistors are only required for the adjustable TPS60500DGS variant - using them with TPS60501DGS would disrupt regulation and is not supported.
How does the power-good (PG) pin behave during startup and shutdown of TPS60501DGS?
During startup, PG remains low until OUT reaches ≥3.201 V (97% of 3.3 V), then pulls high after a 100–200 µs delay. During shutdown (EN = high), PG immediately pulls low. An external pull-up resistor (typically 100 kΩ to VIN or OUT) is mandatory for proper logic-level signaling in both states.
Can TPS60501DGS operate from a single 3.7-V Li-ion cell throughout its discharge curve?
Yes - but only down to ~3.6 V. The TPS60501DGS requires VIN > VOUT + 1.2 V (i.e., >4.5 V) for full 250-mA capability. From 3.7 V to 4.5 V, it operates in 2/3x or LDO mode delivering up to 150 mA. Below 3.6 V, output collapses; thus, it's best paired with cells maintaining ≥3.6 V under load or used with higher-input sources like USB.
What ceramic capacitor values are mandatory for stable operation of TPS60501DGS?
TI specifies CIN = 4.7 µF, C1F = C2F = 1 µF, and COUT ≥10 µF (for ≤150 mA) or ≥22 µF (for 150–250 mA). These values ensure stability across all conversion modes; using smaller capacitors risks oscillation, excessive ripple (>30 mVPP), or premature current limiting - all confirmed in Section 9.2.1.2 of the datasheet.
