Product details
Overview
TPS60240DGKR 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 3.3 V ±2.5% output from 1.8 V to 5.5 V input, supports up to 25 mA load current, achieves 170 µVrms output noise (20 Hz–10 MHz), and operates with 90% peak efficiency - deployed in mobile phone RF sections and SIM module biasing.
For engineers reviewing the TPS60240DGKR datasheet, TPS60240DGKR pinout, TPS60240DGKR application, or TPS60240DGKR equivalent, key selection criteria include ultra-low ripple performance, inductorless operation with only four 1-µF ceramic capacitors, thermal/current protection, shutdown quiescent current of 0.1 µA, and compatibility with battery-powered portable systems requiring tight voltage regulation under varying load and input conditions.
Technical Context
The TPS60240DGKR implements a proprietary 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 surface-mount ceramics while eliminating magnetic components.
It features internal thermal shutdown (trip at 160°C, reset at 140°C) and current limiting, supports logic-level enable control (VIH = 1.3 V, VIL = 0.4 V), and maintains output regulation across –40°C to +85°C ambient temperature with no external compensation required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar switched-capacitor regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60241DGKR | 5-V fixed output; 2.7–5.5 V input range; identical pinout and package | Used where higher VCO tuning voltage or legacy 5-V interface compliance is required | Select when system requires 5-V output and input never drops below 2.7 V |
| MAX864ESA+ | 3.3-V output; 2.0–5.5 V input; SO-8 package; 120 kHz switching; 200 µVrms noise | Higher noise floor and lower efficiency; lacks thermal shutdown | Consider only if VSSOP footprint is unavailable and 30 µVrms noise margin is acceptable |
Compared with TPS60241DGKR, the TPS60240DGKR offers wider input range (1.8 V vs 2.7 V min) for deeper battery discharge support; compared with MAX864ESA+, it delivers superior noise performance, integrated protection, and smaller VSSOP footprint - making it optimal for modern low-power RF subsystems.

FAQ
What is the minimum input voltage required for reliable startup of the TPS60240DGKR?
The TPS60240DGKR guarantees startup at 1.8 V input with ≤5 mA load. At this voltage, it delivers full 3.3 V ±2.5% regulation and maintains operation down to –40°C ambient. Below 1.8 V, output voltage drops proportionally and regulation is not assured - making it ideal for single-cell alkaline or NiMH systems nearing end-of-life.
Does the TPS60240DGKR require external compensation components?
No, the TPS60240DGKR does not require external compensation. Its internal operational amplifier feedback loop and dual-phase charge pump architecture are factory-trimmed for stability with standard 1-µF ceramic capacitors on all terminals (CIN, COUT, C1, C2). Adding compensation risks instability and violates the validated layout guidelines in the datasheet.
How does the TPS60240DGKR achieve 170 µVrms output noise?
The TPS60240DGKR achieves 170 µVrms noise through a dual-phase charge pump topology combined with an op-amp-based feedback control that actively corrects ripple during capacitor discharge cycles. Unlike conventional charge pumps, this architecture eliminates residual ripple from COUT discharge - verified over 20 Hz to 10 MHz bandwidth with 4.7 µF output capacitance.
Can the TPS60240DGKR be used in place of a linear regulator for VCO supply?
Yes, the TPS60240DGKR is explicitly designed as a high-efficiency replacement for inefficient LDOs in VCO supplies. With 90% efficiency and 170 µVrms noise - matching or exceeding many LDOs - it eliminates heat buildup while maintaining phase noise performance. Its 0.1 µA shutdown current further improves system-level power efficiency versus always-on LDOs.
What is the thermal shutdown behavior of the TPS60240DGKR?
The TPS60240DGKR activates thermal shutdown at approximately 160°C junction temperature, disabling switching and reducing input current to near-zero. It automatically recovers when junction temperature falls to ~140°C. This hysteresis prevents cycling near trip point and protects against sustained overload or poor PCB thermal design without requiring external intervention.
