Product details
Overview
TPS60243DGKR from Texas Instruments is a switched-capacitor buck-boost DC-DC 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 over 20 Hz–10 MHz - enabling stable RF bias in mobile phone transceivers.
For engineers reviewing the TPS60243DGKR datasheet, TPS60243DGKR pinout, TPS60243DGKR application, or TPS60243DGKR equivalent, this page details its zero-ripple charge-pump architecture, thermal/current protection, 8-pin VSSOP package constraints, and design trade-offs versus fixed-output alternatives in VCO supply chains.
Technical Context
The TPS60243DGKR implements a dual-phase switched-capacitor topology with an internal op-amp feedback loop that actively suppresses ripple during COUT discharge - eliminating inductor-based EMI while maintaining tight regulation. Its fixed 160 kHz switching frequency enables use of small 1-µF ceramic flying and filter capacitors without external compensation.
It operates in two functional modes: active regulation (EN = high, IQ = 250 µA) and shutdown (EN = low, ISD = 0.1 µA), with built-in thermal shutdown (trip at 160°C, reset at 140°C) and current limiting (80 mA short-circuit protection). Input voltage range is 1.8 V–5.5 V; output is fixed at 3.0 V nominal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±2.5% (2.925–3.075 V) across load, line, and temperature - ensures VCO tuning stability under battery droop. |
| Max Output Current | 25 mA continuous - sufficient for biasing typical cellular-band VCOs and PLL core circuits. |
| Output Noise | 170 µVrms (20 Hz–10 MHz bandwidth) - meets stringent phase-noise requirements in RF front-ends. |
| Efficiency | 81% at IOUT = 10 mA, VIN = 1.8 V - balances low-input operation with minimal thermal rise in space-constrained modules. |
| Quiescent Current | 250 µA typical (active), 0.1 µA typical (shutdown) - extends battery life in always-on RF subsystems. |
| Switching Frequency | 160 kHz typical - allows full use of low-ESR 0805 ceramic capacitors without audible noise or EMI filtering. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and handheld consumer environments. |
Pinout & Package
TPS60243DGKR is housed in an 8-pin VSSOP (DGK) package, 3.0 mm × 3.0 mm × 1.1 mm profile, with exposed thermal pad (not electrically connected). Pin spacing is 0.65 mm; recommended reflow per JEDEC Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.8–5.5 V; requires 1-µF bypass capacitor to GND - sets operating voltage window and ripple rejection baseline. |
| VOUT | Regulated 3-V output | Delivers low-noise 3.0 V to VCO/PLL; must be bypassed with 1-µF ceramic capacitor to GND for ripple suppression. |
| EN | Enable control input | Active-high logic (VIH ≥1.3 V); controls startup/shutdown - enables power sequencing and dynamic RF subsystem enable. |
| GND | Ground reference | Common return for input, output, and flying capacitors - critical for noise integrity; requires low-impedance PCB plane. |
| C1+, C1− | Flying capacitor terminals (Phase 1) | Connect to 1-µF ceramic capacitor (C1); polarity-sensitive - forms first charge-transfer path in dual-phase pump cycle. |
| C2+, C2− | Flying capacitor terminals (Phase 2) | Connect to second 1-µF ceramic capacitor (C2); alternates with C1 to sustain continuous output current and reduce ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-ripple output | 170 µVrms noise over 20 Hz–10 MHz - eliminates need for post-regulation LDOs in sensitive RF bias rails. |
| No-inductor design | Uses only four 1-µF ceramic capacitors - reduces BOM cost, board area, and magnetic coupling risks in compact layouts. |
| Wide input range | Operates from 1.8 V (two-cell alkaline/nickel) to 5.5 V - supports diverse battery chemistries and legacy supply rails. |
| Thermal & current protection | Auto-shutdown at 160°C junction temp; 80 mA current limit - prevents damage during sustained overload or poor heatsinking. |
| Ultra-low shutdown current | 0.1 µA typical - preserves battery charge during idle periods in portable RF modules and SIM card interfaces. |

FAQ
What is the exact output voltage tolerance of the TPS60243DGKR?
The TPS60243DGKR delivers a nominal 3.0-V output with ±2.5% accuracy over full load (0–25 mA), line (1.8–5.5 V), and temperature (–40°C to +85°C) conditions - meaning output remains within 2.925 V to 3.075 V. This tight tolerance ensures reliable VCO tuning voltage across battery discharge and environmental variation, and is verified per TI's SLVS372C datasheet Section 6.5.
Does the TPS60243DGKR require external compensation components?
No, the TPS60243DGKR does not require external compensation. Its internal op-amp feedback loop and fixed-frequency dual-phase charge-pump architecture are fully self-contained. Only four external 1-µF ceramic capacitors (CIN, COUT, C1, C2) are needed - eliminating inductors, resistors, and compensation networks required by traditional DC-DC controllers.
Can the TPS60243DGKR operate from a single 1.8-V alkaline cell?
Yes, the TPS60243DGKR supports input voltages as low as 1.8 V and is explicitly characterized for operation from two-cell alkaline or nickel-based batteries. At VIN = 1.8 V and IOUT = 10 mA, it maintains 81% efficiency and regulated 3.0-V output - making it suitable for space-constrained, battery-powered RF modules where input headroom is minimal.
How does the TPS60243DGKR achieve 170-µVrms output noise?
The TPS60243DGKR achieves 170 µVrms output noise through a proprietary dual-phase charge-pump topology combined with an internal op-amp in the feedback loop. This architecture actively cancels ripple during COUT discharge - unlike single-phase pumps - and eliminates the need for post-regulation LDOs. Performance is measured over 20 Hz–10 MHz with 1-µF ceramic capacitors per TI SLVS372C Figure 22.
Is the TPS60243DGKR pin-compatible with other TPS6024x variants?
Yes, all TPS6024x devices - including TPS60240DGKR (3.3 V), TPS60241DGKR (5 V), TPS60242DGKT (2.7 V), and TPS60243DGKR (3 V) - share identical 8-pin VSSOP (DGK) packaging and pinout. This allows direct substitution in existing layouts when output voltage requirements change, provided the new variant's input range and load capability meet system needs.
