Model:MCP1640DT-ICHY
Manufacturer：Microchip Technology
Stocks：20000
Describe：
0.65V startup and synchronous boost DC-DC converter. It can efficiently boost the low voltage obtained from a single or multiple batteries (alkaline, nickel-metal-hydride, lithium-ion, etc.) to a stable output voltage of 2V to 5.5V, providing power for portable devices.
Features ：
• Extremely low startup voltage: The typical startup voltage is as low as 0.65V, and the operating voltage can be as low as 0.35V.
• High efficiency: The efficiency can reach up to 96%, using synchronous rectification technology and featuring built-in low-on-resistance switching tubes.
• Adjustable output: The output voltage can be adjusted within the range of 2V to 5.5V, with an output current of 350mA.
• Operating mode: Fixed 500kHz switching frequency, supporting automatic PFM/PWM mode switching, maintaining high efficiency under light load.
• True load isolation: In the off state, it can truly disconnect the input from the output, preventing battery leakage.
• Wide operating temperature range: Industrial-grade temperature range of -40°C to +125°C.
• Small package: Using SOT-23-6 surface mount packaging, saving PCB space.
Application：
It is widely used in various battery-powered portable products, such as: wireless sensors, handheld instruments, GPS receivers, Bluetooth headphones, personal medical devices, and single-cell lithium-ion battery to 5V converters, etc.
