LTC3410 Summary of contents
Page 1
... The device is available in adjustable and fixed output voltage versions. Supply current during operation is only 26µA, dropping to <1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3410 ideally suited for single Li-Ion battery-powered applica- tions. 100% duty cycle provides low dropout operation, extending battery life in portable systems ...

... Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LTC3410E is guaranteed to meet performance specifications from 0°C to 85°C. Specifications over the –40°C to 85°C operating temperature range are assured by design, characterization and correlation with statistical process controls ...

... R increases (see Typical Performance Characteristics). Therefore, the user should calculate the power dissipation when the LTC3410 is used at 100% duty cycle with low input voltage (See Thermal Considerations in the Applica- tions Information section). Slope Compensation and Inductor Peak Current ...

... A R where T is the ambient temperature example, consider the LTC3410 in dropout at an input voltage of 2.7V, a load current of 300mA and an ambient temperature of 70°C. From the typical perfor- mance graph of switch resistance, the R P-channel switch at 70°C is approximately 1.0Ω. Therefore, power dissipated by the part is: ...
