Product details
Overview
TPS60243DGKTG4 from Texas Instruments is a switched-capacitor buck-boost converter optimized for low-noise voltage-controlled oscillator (VCO) and phase-locked loop (PLL) power supplies. It delivers a regulated 3-V output with ±2.5% accuracy, supports 1.8 V to 5.5 V input, provides up to 25 mA output current, and achieves 170 µVrms output noise (20 Hz–10 MHz bandwidth) - enabling stable RF biasing in mobile phone transceivers.
For engineers reviewing the TPS60243DGKTG4 datasheet, TPS60243DGKTG4 pinout, TPS60243DGKTG4 application, or TPS60243DGKTG4 equivalent, key selection criteria include zero-ripple performance under dynamic load, thermal shutdown behavior at 160°C, shutdown current of 0.1 µA, compatibility with only ceramic capacitors (no inductor), and operation in the 8-pin VSSOP package with 1.1-mm height.
Technical Context
The TPS60243DGKTG4 implements a dual-phase charge pump architecture with an integrated operational amplifier in the feedback loop to actively suppress ripple during capacitor discharge cycles. Its fixed 160 kHz switching frequency enables use of small 1-µF ceramic flying and output capacitors while maintaining tight regulation across input voltages from 1.8 V to 5.5 V.
It operates in two functional modes: active regulation (EN high) with 250 µA quiescent current and shutdown (EN low) with 0.1 µA supply current. Thermal protection disables switching above 160°C junction temperature and resumes at 140°C, while internal current limiting caps output at 80 mA under short-circuit conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±2.5% - tightly regulated for VCO/PLL reference stability across load and temperature |
| Input Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion, NiMH, alkaline, and 3.3-V system rails |
| Max Output Current | 25 mA continuous - sufficient for biasing RF synthesizers and low-power PLL cores |
| Output Noise | 170 µVrms (20 Hz–10 MHz) - enables clean VCO tuning voltage without phase noise degradation |
| Efficiency | 81% at 10 mA / 1.8 V input - high conversion efficiency preserves battery life in portable devices |
| Shutdown Current | 0.1 µA typical - minimizes standby power in always-on RF subsystems |
| Switching Frequency | 160 kHz nominal - allows compact 1-µF ceramic capacitors and avoids EMI-sensitive bands |
Pinout & Package
TPS60243DGKTG4 is housed in an 8-pin VSSOP (DGK) package with 0.65-mm pitch and 1.1-mm maximum height, optimized for space-constrained RF modules and handheld PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 1.8–5.5 V supply; requires 1-µF bypass capacitor to GND for stability |
| VOUT | Regulated output | Delivers 3.0 V ±2.5%; must be bypassed with 1-µF ceramic capacitor to GND |
| EN | Enable control | Active-high logic input; drives device into 0.1 µA shutdown when low |
| GND | Ground reference | Common return path for input, output, and flying capacitors; critical for noise control |
| C1+, C1− | Flying capacitor terminals | Connect external 1-µF ceramic capacitor (C1); polarity-sensitive charge transfer nodes |
| C2+, C2− | Flying capacitor terminals | Connect second external 1-µF ceramic capacitor (C2); interleaved with C1 for ripple cancellation |
Key Features
| Feature | Design Value |
|---|---|
| Zero-ripple output | 170 µVrms noise over 20 Hz–10 MHz enables direct VCO powering without LC filtering |
| No-inductor design | Eliminates magnetic EMI and board area overhead; uses only four 1-µF ceramic capacitors |
| Ultra-low shutdown current | 0.1 µA ensures negligible battery drain during sleep mode in portable RF systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switched-capacitor regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60242DGKT | 2.7-V fixed output (vs. 3.0 V); identical pinout, package, and noise performance | Suitable where system-level VCO/PLL requires 2.7 V instead of 3.0 V; same layout reuse possible | Select when target bias voltage matches 2.7 V specification and ±2.5% tolerance is acceptable |
| TPS60240DGKT | 3.3-V fixed output (vs. 3.0 V); shares same thermal shutdown, shutdown current, and capacitor requirements | Used in 3.3-V-centric RF subsystems; higher output may require downstream LDO or resistor divider | Choose if existing design uses 3.3-V VCOs and board layout accommodates same 8-pin VSSOP footprint |
Compared with TPS60242DGKT and TPS60240DGKT, the TPS60243DGKTG4 provides the only 3.0-V option in the family - making it essential for RF ICs specifying 3.0-V nominal VCO supply, while retaining identical noise, efficiency, and thermal characteristics across all three variants.

FAQ
What is the output voltage accuracy of the TPS60243DGKTG4?
The TPS60243DGKTG4 delivers a regulated 3.0-V output with ±2.5% accuracy across load (0–10 mA), input voltage (1.8–5.5 V), and temperature (–40°C to +85°C). This tolerance is specified in the Electrical Characteristics table of the SLVS372C datasheet and ensures reliable operation for VCOs requiring tight supply voltage control. The TPS60243DGKTG4 maintains this accuracy without external trimming components.
Does the TPS60243DGKTG4 require an inductor?
No, the TPS60243DGKTG4 is a switched-capacitor converter and uses only four external ceramic capacitors - two 1-µF flying capacitors (C1, C2) and one each for input (CIN) and output (COUT). Its dual-phase charge pump architecture eliminates inductors entirely, reducing EMI, board area, and cost compared to inductive DC-DC solutions. This makes the TPS60243DGKTG4 ideal for space- and noise-sensitive RF layouts.
What is the shutdown current of the TPS60243DGKTG4?
The TPS60243DGKTG4 draws 0.1 µA typical current in shutdown mode when the EN pin is driven low. This ultra-low quiescent draw is confirmed in Section 6.5 of the SLVS372C datasheet under "IQ" (Quiescent Current) test conditions. The TPS60243DGKTG4 exits shutdown automatically when EN returns high, with a typical start-up time of 0.5 ms to reach 90% of nominal output voltage.
Can the TPS60243DGKTG4 operate from a 1.8-V input?
Yes, the TPS60243DGKTG4 supports input voltages from 1.8 V to 5.5 V, as stated in Section 6.3 (Recommended Operating Conditions) of the SLVS372C datasheet. At 1.8-V input and 10-mA load, it achieves 81% efficiency and maintains full 3.0-V output regulation. This capability enables direct operation from single-cell alkaline, NiMH, or Li-ion batteries without pre-regulation.
What is the output noise performance of the TPS60243DGKTG4?
The TPS60243DGKTG4 delivers 170 µVrms output noise measured over a 20 Hz to 10 MHz bandwidth, per Section 6.5 of the SLVS372C datasheet. This "zero-ripple" specification results from its dual-phase charge pump with op-amp feedback, which actively cancels residual switching artifacts. The TPS60243DGKTG4 achieves this performance using standard 1-µF ceramic capacitors without additional filtering.
