Product details
Overview
TPS60241DGKRG4 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 5-V output with ±2.5% accuracy, supports 2.7–5.5-V input, provides up to 25-mA output current, achieves 170-µVrms output noise (20 Hz–10 MHz), and operates in an 8-pin VSSOP package for space-constrained RF modules.
For engineers reviewing the TPS60241DGKRG4 datasheet, TPS60241DGKRG4 pinout, TPS60241DGKRG4 application, or TPS60241DGKRG4 equivalent, key selection criteria include ultra-low ripple performance, inductorless operation, thermal shutdown behavior, enable-controlled shutdown mode (0.1 µA), and compatibility with ceramic-only external components (four 1-µF caps).
Technical Context
The TPS60241DGKRG4 implements a proprietary dual-phase charge pump architecture with operational amplifier feedback control to eliminate switching ripple during COUT discharge. Its fixed 160-kHz internal oscillator drives interleaved flying capacitor (C1/C2) switching, enabling zero-ripple regulation without inductors.
It integrates thermal shutdown (trip at ~160°C, reset at ~140°C), current limiting (~80 mA short-circuit), and logic-level enable control (VIH ≥ 1.3 V, VIL ≤ 0.4 V). The device maintains regulation across –40°C to +85°C ambient while drawing only 250 µA quiescent current in active mode.
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 | Same silicon, identical electrical specs; differs only in tape-and-reel packaging (2500 vs. 250 units) and marking (AUB vs. AUBG4) | No functional difference; both support same VCO/PLL use cases and PCB layout | Select DGKR for high-volume production; DGKRG4 is functionally identical with G4 suffix indicating green/RoHS-compliant finish |
| MAX862ESA+ | 5-V fixed-output charge pump, but higher 250-µVrms noise, lower 15-mA output, no thermal shutdown | Lacks integrated protection and fails to meet stringent phase-noise budgets in modern RF designs | Only suitable for legacy or cost-sensitive non-critical biasing where 170-µVrms and thermal safety are not required |
Compared with TPS60241DGKR and MAX862ESA+, the TPS60241DGKRG4 offers superior noise performance (170 vs. 250 µVrms), higher output current (25 vs. 15 mA), and integrated thermal/current protection-making it the preferred choice for next-generation RF power management where signal integrity and reliability are paramount.

FAQ
What is the maximum continuous output current of the TPS60241DGKRG4?
The TPS60241DGKRG4 delivers up to 25 mA of continuous output current under recommended operating conditions (VIN ≥ 2.7 V, TA ≤ 85°C). At higher temperatures or lower input voltages, the maximum sustainable current decreases-e.g., ~12 mA at VIN = 2.7 V and TA = 85°C per Figure 24 in the datasheet. This rating ensures stable 5-V regulation for VCO core biasing without thermal derating in handheld RF applications.
Does the TPS60241DGKRG4 require external inductors?
No, the TPS60241DGKRG4 is an inductorless switched-capacitor converter. It uses only four external ceramic capacitors (CIN, COUT, C1, C2)-each typically 1 µF-to achieve buck-boost conversion. This eliminates magnetic components, reduces EMI, simplifies layout, and avoids inductor saturation or audible coil whine-critical advantages for noise-sensitive VCO and PLL power domains.
How does the TPS60241DGKRG4 achieve 170-µVrms output noise?
The TPS60241DGKRG4 achieves 170-µVrms output noise through its dual-phase charge pump architecture combined with an op-amp-based feedback loop. Unlike standard charge pumps, this design actively regulates during COUT discharge, eliminating ripple at the fundamental switching frequency and harmonics. Measured over 20 Hz–10 MHz bandwidth with 4.7-µF COUT, this performance directly supports low-phase-noise RF synthesis in cellular and wireless applications.
What is the purpose of the EN pin on the TPS60241DGKRG4?
EN is an active-high enable pin that controls device operation. When pulled high (≥1.3 V), the TPS60241DGKRG4 powers up with ~0.5-ms start-up time to 90% VOUT. When pulled low (≤0.4 V), it enters shutdown mode, reducing input current to 0.1 µA and disconnecting the load from VOUT. This allows precise power gating in battery-powered systems-e.g., disabling VCO bias between transmission bursts to extend runtime.
Is the TPS60241DGKRG4 compatible with ceramic-only external components?
Yes, the TPS60241DGKRG4 is fully compatible with ceramic-only external components: one 1-µF input capacitor (CIN), one 1-µF output capacitor (COUT), and two 1-µF flying capacitors (C1, C2). TI recommends X7R/X5R dielectrics in 0805 packages with ≤0.1 Ω ESR. This ceramic-only BOM eliminates electrolytics and tantalums, improving reliability, temperature stability, and long-term capacitance retention in portable RF equipment.
