Overview
The LT1610CS8#PBF is a high-efficiency, step-up DC/DC converter manufactured by Analog Devices Inc. It operates from a single lithium cell or low-voltage source, supporting an input voltage range of 900 mV to 8 V. The device delivers up to 300 mA output current with a maximum output voltage of 28 V. Key electrical parameters include a switching frequency of 1.7 MHz, quiescent current of 30 uA, and shutdown current of 1 uA. It features thermal shutdown protection and is housed in an 8-lead SOIC package.
Feature Summary
- Integrated 1.7 MHz switching frequency enables the use of small external components for compact designs.
- Ultra-low quiescent current of 30 uA maximizes battery life in portable applications.
- Operates efficiently from a single-cell lithium battery or low-voltage input sources.
- Includes thermal shutdown protection to safeguard the device during overload conditions.
Applications
- Portable medical devices requiring extended battery operation
- Single-cell lithium battery powered systems
- Low-voltage microprocessor supply generation
- Handheld instrumentation
Procurement Notes
Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the SOIC-8 package type matches your PCB footprint requirements. Check current availability status as distribution may vary. Ensure input voltage ranges align with your power source specifications before integration.
Selection Notes
Select this component when designing for single-cell lithium applications requiring high efficiency at light loads. The 1.7 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 300 mA output limit for load requirements. Verify thermal performance within the specified operating temperature range of 0 C to +75 C.
Part Context
This part belongs to the LT1610 family of micropower step-up converters. It is designed specifically for applications powered by a single lithium cell. The CS8 package variant denotes the commercial temperature grade and SOIC-8 physical form factor used in surface-mount assemblies.
Replacement Considerations
LT1610ES8#PBF: Same functional specifications but in an SSOP-8 package instead of SOIC-8. Verify pin compatibility and board space constraints before substitution.
