LT1110CS8-12#PBF

Overview

The LT1110CS8-12#PBF is a micropower DC-DC converter manufactured by Analog Devices Inc. It operates with input voltages ranging from 1V to 30V and provides a fixed 12V output. The device supports both step-up and step-down topologies within an SOIC-8 package. Key electrical parameters include a quiescent current of 300µA, a switching frequency of 70kHz, and an internal power switch rated for 1A. It requires only three external components for operation.

Feature Summary

• Versatile micropower DC-DC converter requiring only three external off-the-shelf components
• Operates in step-up or step-down mode with low-battery detector comparator
• On-chip user-adjustable current limit and internal 1A power switch

Applications

• Single cell battery powered applications
• Remote systems requiring minimum current consumption
• Laser diode drivers

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific suffix matches the required packaging and temperature grade. Check current availability status as supply may be limited. Ensure the datasheet revision aligns with design requirements before finalizing procurement orders.

Selection Notes

Select this part when a fixed 12V output is required from varying input sources between 1V and 30V. Consider the LT1111 for most step-down applications where the input source exceeds 3V. Evaluate the 300µA quiescent current against system standby requirements. Verify that the 70kHz switching frequency suits the available passive component sizes.

Part Context

This component belongs to the LT1110 series of micropower DC-DC converters. It is designed for space-saving applications using the 8-pin MiniDIP or S8 package. The series offers fixed or adjustable output voltage versions suitable for battery-operated devices.

Replacement Considerations

LT1111 is recommended for most step-down applications or input sources greater than 3V.
