Linear Technology's LTC3607EMSE#TRPBF Dual Channel Synchronous Buck Regulator

The LTC3607EMSE#TRPBF is a high-performance, dual-channel synchronous buck regulator designed by Linear Technology, now part of Analog Devices. This compact and efficient power management IC is ideal for portable device applications due to its low quiescent current and the ability to generate two independent output voltages from a single input.

Key Features:

• Wide Input Voltage Range: The device can operate from an input voltage range of 4.5V to 15V, making it versatile for various applications.
• Dual Independent Outputs: It offers two outputs that can be adjusted from 0.6V to VIN, with output current capabilities of up to 1.5A for each channel.
• High Efficiency: The LTC3607EMSE#TRPBF utilizes low RDS(ON) internal switches which contribute to its high efficiency, a critical feature for battery-powered devices.
• Selectable Switching Frequency: The switching frequency can be programmed between 300kHz and 3MHz or synchronized to an external clock, allowing for flexibility in balancing efficiency and external component size.
• 100% Duty Cycle: Low dropout operation is possible with a 100% duty cycle, which is beneficial during low battery conditions.
• Stable with Ceramic Capacitors: The regulator is stable with ceramic output capacitors, which are smaller, have lower ESR, and are more reliable over temperature compared to electrolytic capacitors.
• Thermal Protection: It includes internal thermal protection to safeguard the device under high-temperature conditions.
• Compact Package: The LTC3607EMSE#TRPBF is offered in a compact 16-lead MSOP package, which is ideal for space-constrained applications.
