Product details
Overview
TPS60500DGSG4 from Texas Instruments is an adjustable-output, high-efficiency step-down charge pump DC-DC converter optimized for space-constrained battery-powered systems. It delivers up to 250 mA at an output voltage programmable from 0.8 V to 3.3 V across a 1.8 V–6.5 V input range, with 90% peak efficiency and integrated power-good supervision - used in portable instrumentation and USB-powered peripherals requiring compact, low-quiescent-power regulation.
For engineers reviewing the TPS60500DGSG4 datasheet, TPS60500DGSG4 pinout, TPS60500DGSG4 application, or TPS60500DGSG4 equivalent, key selection criteria include its adjustable output configuration (FB-based feedback), 10-pin VSSOP package footprint, multi-mode fractional conversion (LDO/2/3x/0.5x/1/3x), thermal/overcurrent protection, and soft-start behavior during enable transitions.
Technical Context
The TPS60500DGSG4 implements switched-capacitor fractional conversion using two flying capacitors (C1F, C2F) and internal MOSFET switch arrays to achieve regulated output without inductors. Its control architecture dynamically selects among LDO, 2/3x, 0.5x, and 1/3x conversion modes based on VIN/VOUT ratio and load current - enabling >90% efficiency across wide input/output combinations while maintaining <3% output voltage tolerance over line, load, and temperature.
Regulation is achieved via an error amplifier comparing FB voltage to a 0.8-V internal reference; for the TPS60500DGSG4, FB requires an external resistor divider to set output voltage. The device integrates power-good detection (open-drain PG), thermal shutdown (150°C trip), short-circuit current limiting (300 mA typical), and <40 µA quiescent current in active operation - all within a micro-small 3.05 mm × 4.98 mm VSSOP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Adjustable 0.8 V to 3.3 V via FB pin; enables single BOM for multiple rail requirements without changing IC. |
| Max Output Current | 250 mA at VOUT ≥ 1.5 V and VIN > VOUT + 1.2 V; supports mid-power digital loads like DSP cores and interface I/O. |
| Input Voltage Range | 1.8 V to 6.5 V; compatible with single Li-ion (2.7–4.2 V), dual alkaline (2.4–3.2 V), or USB 5-V sources. |
| Peak Efficiency | 90% at 150 mA; reduces thermal stress and extends battery life in portable applications. |
| Quiescent Current | 40 µA typical at no load; critical for always-on subsystems and low-duty-cycle sensing nodes. |
| Switching Frequency | 600–1200 kHz; enables use of small 1-µF ceramic flying capacitors and minimizes EMI filtering complexity. |
| Output Voltage Tolerance | ±3% over line, load, and −40°C to +125°C junction temperature; ensures reliable logic-level compliance. |
Pinout & Package
TPS60500DGSG4 uses a 10-pin VSSOP package (3.05 mm × 4.98 mm body size) with exposed thermal pad (not electrically connected). Pin functions are validated per TI SLVS391C Rev. C datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-low logic control; pulling high disables device, reducing input current to 0.05 µA and isolating load from battery. |
| PG (Pin 2) | Power-good open-drain output | Asserts high when OUT reaches ≥97% nominal voltage; requires external pullup to monitor system power readiness. |
| C2F− (Pin 3) | Flying capacitor C2F negative terminal | Connects to ground side of second flying capacitor; critical path for 0.5x/1/3x mode energy transfer. |
| C2F+ (Pin 4) | Flying capacitor C2F positive terminal | Connects to switching node for C2F charging/discharging cycles; shares layout sensitivity with C1F pins. |
| VIN (Pin 5) | Main input supply | Accepts 1.8–6.5 V; requires 2.2-µF ceramic input capacitor (Ci) close to pin for stability and ripple suppression. |
| C1F+ (Pin 6) | Flying capacitor C1F positive terminal | Primary switching node for first flying capacitor; phase-aligned with C2F+ in 2/3x and 1/3x modes. |
| OUT (Pin 7) | Regulated output | Delivers final regulated voltage; bypassed with ≥10-µF ceramic capacitor (Co) to minimize ripple and ensure loop stability. |
| C1F− (Pin 8) | Flying capacitor C1F negative terminal | Ground return for C1F; must be routed with low-inductance path to GND plane to avoid switching noise coupling. |
| GND (Pin 9) | Power ground | Common reference for all analog and power circuits; requires solid thermal and low-impedance PCB connection. |
| FB (Pin 10) | Feedback input | Connects to voltage divider between OUT and GND; sets output via 0.8-V internal reference - unique to TPS60500 variant. |
Key Features
| Feature | Design Value |
|---|---|
| Multi-mode fractional conversion | Automatically selects LDO / 2/3x / 0.5x / 1/3x modes to maintain >85% efficiency across 1.8–6.5 V input and 0.8–3.3 V output ranges. |
| Integrated power-good supervisor | Open-drain PG pin asserts high within 100–200 µs after OUT reaches 97% of target, enabling safe system sequencing and reset control. |
| Thermal and short-circuit protection | Shuts down at 150°C junction temperature and limits start-up current to 300 mA; prevents damage during fault conditions. |
| Load isolation in shutdown | Disables internal switches and blocks current path from VIN to OUT when EN = high, extending battery shelf life in standby. |
| Low-noise, capacitor-only design | Eliminates inductors entirely - uses only four ceramic capacitors (Ci, C1F, C2F, Co) for full regulation, reducing EMI and board area. |

FAQ
What output voltage range does the TPS60500DGSG4 support, and how is it set?
The TPS60500DGSG4 supports an adjustable output voltage from 0.8 V to 3.3 V. This is set externally using a resistor divider connected between OUT and GND, with the midpoint feeding the FB pin. The internal 0.8-V reference determines VOUT = 0.8 V × (1 + R1/R2), enabling precise rail tuning without changing the IC. Unlike fixed-output variants (e.g., TPS60501DGSG4), the TPS60500DGSG4 requires this divider for all configurations.
How does the TPS60500DGSG4 manage efficiency across varying input voltages?
The TPS60500DGSG4 automatically selects among LDO, 2/3x, 0.5x, and 1/3x conversion modes based on the VIN/VOUT ratio and load current. For example, at VIN = 5 V and VOUT = 1.5 V, it engages 1/3x mode to achieve ~87% efficiency; at VIN = 2.5 V and VOUT = 1.8 V, it defaults to LDO mode with ~82% efficiency. This dynamic mode selection maintains >85% efficiency across its full operating range without user intervention.
What protection features are integrated into the TPS60500DGSG4?
The TPS60500DGSG4 integrates thermal shutdown (150°C trip), output short-circuit current limiting (300 mA typical during start-up), and overcurrent protection that reduces output current above 500 mA. It also provides load isolation during shutdown (EN = high), limiting leakage to ≤1 µA from OUT to GND - critical for preserving battery shelf life in always-connected devices.
Can the TPS60500DGSG4 operate from a single alkaline cell?
Yes - the TPS60500DGSG4 operates from 1.8 V to 6.5 V, covering the full discharge curve of a single alkaline cell (1.0–1.6 V nominal, up to 1.65 V fresh). At 1.8 V input, it delivers up to 50 mA at 1.5 V output in LDO mode. For higher currents, input must exceed VOUT + 1 V (e.g., ≥2.5 V for 1.5 V out), making it viable for low-power sensor nodes powered by one AA/AAA cell.
What is the role of the PG pin on the TPS60500DGSG4, and how should it be used?
The PG (power good) pin on the TPS60500DGSG4 is an open-drain output that goes high when the OUT voltage reaches ≥97% of its nominal value. It requires an external pullup resistor (typically to VIN or OUT) and is used to signal system controllers or sequencers that regulated power is stable. In shutdown (EN = high), PG is actively pulled low - enabling reliable reset assertion during power transitions.
