The LTC3564IDCB#TRPBF is a high-performance, quad-channel, constant-frequency, synchronous buck regulator from Linear Technology. This advanced power management integrated circuit (IC) is designed to provide precise voltage regulation with high efficiency, making it an ideal solution for portable electronic devices where extended battery life and compactness are critical.

Key Features

• Multiple Output Channels: Features four independent DC/DC converters that can supply up to 600mA of output current each.
• High Efficiency: Synchronous rectification offers efficiency as high as 95%, which helps in reducing heat generation and improving battery life.
• Adjustable Output Voltage: Output voltages are adjustable down to 0.6V, allowing for a wide range of applications and compatibility with modern low-voltage digital devices.
• Stable with Ceramic Capacitors: Designed to be stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than other types.
• Low No-load Quiescent Current: Exhibits a low quiescent current under no-load conditions, contributing to battery conservation when the device is in standby mode.
• Programmable Switching Frequency: The switching frequency can be programmed between 1MHz and 2.25MHz or synchronized to an external clock, allowing for flexibility in design and optimization of component sizes.
• Thermal Protection: Includes over-temperature protection to safeguard the device under abnormal thermal conditions.
