Overview
The TK65025MTL is a low power step-up DC-DC converter manufactured by TOKO, Inc. It operates from a single battery cell down to 0.9 V input and boosts the voltage to a regulated 3 V output. The device integrates a high-efficiency MOS switch, internal bandgap reference, and pulse burst modulation regulation. Key electrical characteristics include very low quiescent current, laser-trimmed output voltage, and undervoltage lockout. It features a microprocessor reset output and is housed in a SOT-23L-6 package.
Feature Summary
- Integrates a high-efficiency MOS switching element for boost conversion
- Operates with input voltages as low as 0.9 V
- Includes an internal bandgap reference for stable regulation
- Provides a dedicated microprocessor reset output signal
Applications
- Battery-powered portable systems
- Cellular telephones
- Pagers
- Personal communications equipment
- Portable instrumentation
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the SOT-23L-6 specification. Check for obsolescence status as indicated in distributor records. Ensure storage conditions comply with moisture sensitivity levels. Validate that the specific suffix matches the required operational parameters.
Selection Notes
Select this component when designing circuits requiring a fixed 3 V output from a single-cell lithium or alkaline battery source. Consider its low quiescent current for extended battery life in standby modes. Evaluate the need for the integrated reset function for microprocessor control. Compare thermal performance and efficiency requirements against alternative boost converters in similar packages.
Part Context
This part belongs to the TK6502x series of step-up voltage converters from TOKO, Inc. It shares functional similarities with models like the TK65020 but offers specific output voltage and monitoring features. The series is designed for portable consumer electronics where space and power efficiency are critical constraints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative manufacturers.
