MCP1650S-E/MS 750 kHz Gated Oscillator Boost DC-DC Controller IC
The MCP1650S-E/MS is a 750 kHz gated oscillator boost DC-DC controller developed by Microchip Technology, engineered for high-power portable and automotive applications requiring efficient step-up voltage conversion. Packaged in a compact 8-pin MSOP package, this device delivers up to 5 watts of output power while consuming only 120 µA of quiescent current at no load, making it exceptionally power-efficient. Operating from an input voltage range of 2.0V to 5.5V, it supports outputs from 3.3V to over 100V with a maximum output current of 100mA. The controller utilizes an external N-channel MOSFET, Schottky diode, and boost inductor to achieve high-output power conversion.
The MCP1650S-E/MS is well-suited for a broad spectrum of applications requiring efficient high-voltage step-up conversion from low-voltage sources. Primary application areas include high-power boost converters for portable devices, where its low quiescent current and high efficiency extend battery life. The device is ideal for high-voltage bias supplies, white LED drivers and flashlights, and local power conversion such as 3.3V-to-5V, 3.3V-to-12V, and 5V-to-12V boost stages. Automotive power management systems benefit from its AEC-Q100 qualification and wide temperature range. Additional applications include distributed power systems, intelligent lighting systems, plug-and-play solar-powered equipment, remote sensing applications, battery chargers, and motor control systems.
Frequently Asked Questions
Q: What is the maximum output power the MCP1650S-E/MS can deliver?
A: The device can deliver up to 5 watts of output power to the load when properly configured with appropriate external components.
Q: What external components are required for a boost converter design?
A: The controller requires an external N-channel MOSFET, a Schottky diode, and a boost inductor to complete the power conversion stage. The high 750 kHz switching frequency allows for the use of smaller inductors and capacitors.
Q: What is the difference between the MCP1650S and MCP1650R variants?
A: The MCP1650S features a UVLO threshold of 2.55V, while the MCP1650R has a UVLO threshold of 2.0V, allowing designers to select the appropriate undervoltage protection level for their specific battery or supply characteristics.
