LT1302CS8-5#PBF

Overview

The LT1302CS8-5#PBF is a micropower high-efficiency boost DC/DC converter manufactured by Analog Devices. It operates with an input voltage range of 2 V to 8 V and provides a fixed output voltage of 5 V. The device delivers a maximum output current of 2 A while maintaining a quiescent current of 200 uA. It functions at a switching frequency of 400 kHz and includes shutdown control. The component is housed in an 8-pin SOIC package and supports operation within a temperature range of 0°C to +70°C.

Feature Summary

• Integrates a low quiescent current boost regulator for efficient power management
• Provides high output current capability up to 2 A
• Includes integrated shutdown functionality for power control

Applications

• Portable battery-powered equipment requiring step-up conversion
• Systems utilizing single-cell lithium-ion or alkaline batteries
• Micropower applications demanding high efficiency from low input voltages

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required pinout and electrical specifications. Confirm that the fixed 5 V output variant matches the design requirements, as other versions may offer adjustable outputs. Cross-reference the SOIC-8 package dimensions and thermal characteristics with the target PCB layout constraints prior to finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5 V output is required from inputs between 2 V and 8 V. It is suitable for designs needing up to 2 A load current with minimal standby power consumption. Consider the 400 kHz switching frequency for inductor sizing and EMI management. Ensure the operating environment stays within the specified commercial temperature range.

Part Context

This part belongs to the LT1302 series of micropower high-efficiency DC/DC converters. The CS8 designation indicates the commercial temperature grade and SOIC-8 surface mount package. The -5 suffix specifies the fixed 5 V output version, distinguishing it from adjustable variants within the same family.
