LTC3526LEDC#TRPBF - High-Efficiency Step-Up DC/DC Converter

The LTC3526LEDC#TRPBF is a compact, high-efficiency, fixed-frequency step-up DC/DC converter from Linear Technology designed to meet the stringent power requirements of modern portable devices. This device is capable of generating a stable output voltage from an input voltage as low as 0.85V, making it ideal for single-cell, multi-cell, or Li-Ion battery-powered applications where the input voltage can fall below the nominal output voltage level.

Key Features:

• Adjustable Output Voltage: The LTC3526LEDC#TRPBF allows for an adjustable output voltage range from 1.5V to 5.25V, which can be set by external resistors. This flexibility makes it suitable for powering a wide variety of devices.
• High Efficiency: With up to 94% conversion efficiency, this step-up converter ensures minimal power loss and maximizes battery life.
• Low Quiescent Current: The device features a low quiescent current of only 7µA, which is particularly beneficial for battery-powered applications where power conservation is critical.
• High Switching Frequency: The LTC3526LEDC#TRPBF operates at a fixed 1MHz switching frequency, allowing the use of small, low-cost capacitors and inductors while minimizing the overall footprint of the power supply design.
• Burst Mode® Operation: For further power savings, the device offers Burst Mode operation, which reduces quiescent current during light loads, thus extending battery runtime.
• Integrated Soft-Start: The soft-start feature limits inrush current during startup, which helps prevent input current overshoot and the associated problems.

Applications:

The LTC3526LEDC#TRPBF is suitable for a vast array of applications, including but not limited to:

• Portable Medical Devices
• Wireless Headsets
• MP3 Players
• Portable Instruments
• Handheld Computers

With its tiny footprint and high-efficiency design, the LTC3526LEDC#TRPBF is an excellent choice for designers looking to optimize power consumption and extend battery life in compact, portable devices.
