TPS60300DGS

Voltage Regulators - DC DC Switching Regulators Overview

The TPS60300DGS is a high-efficiency, inductorless charge pump DC/DC converter manufactured by Texas Instruments. It provides dual regulated outputs of 3.0 V and 3.3 V from a single-cell input source ranging from 0.9 V to 1.8 V. The device delivers up to 20 mA per output channel with a typical operating supply current of 35 µA. It operates at a switching frequency of 700 kHz and is housed in a 10-pin VSSOP package. The component supports an extended industrial temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Dual-output architecture providing independent 3.0 V and 3.3 V rails from a single low-voltage source
• Inductorless charge pump topology eliminates the need for bulky magnetic components
• Ultra-low quiescent current design optimizes battery life in portable applications
• Integrated boost regulation maintains stable output voltages across varying input conditions

Voltage Regulators - DC DC Switching Regulators Applications

• Powering dual-rail logic circuits in single-cell battery devices
• Supplying voltage for RF transceivers requiring specific positive rail configurations
• Portable medical instrumentation utilizing single-cell lithium-ion power sources
• Handheld communication devices needing efficient step-up conversion without inductors

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'DGS' corresponds to the tube packaging format rather than the reel variant 'DGSR'. Confirm that the specific output configuration matches the required 3.0 V and 3.3 V levels, as other family members may offer different voltage combinations or current capabilities. Ensure the application environment remains within the specified -40°C to +85°C operational temperature limits for reliable performance.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a dual-output solution is strictly required from a single-cell input, eliminating the complexity of separate regulators. The absence of an inductor makes it suitable for space-constrained designs where magnetic interference must be minimized. Compare against the TPS60301 if higher output current or different voltage options are needed, noting that the TPS60300 is optimized specifically for the 20 mA dual-output requirement.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6030x series of single-cell charge pumps designed for efficiency and compactness. It complements other Texas Instruments PMICs like the TPS60200 series, which typically offers single outputs or different current ratings. The VSSOP-10 package allows for surface-mount integration, fitting into modern consumer electronics layouts where board area is at a premium compared to older through-hole or larger SOT packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS60300DGSR serves as the identical functional alternative packaged in a tape-and-reel format for automated assembly. For applications requiring higher current, the TPS60301 provides similar dual-output functionality with increased capacity. Single-output variants such as the TPS60310 may be considered if only one regulated rail is necessary.
