Microchip Technology MCP1650R-E/MS Product Overview

The MCP1650R-E/MS is a high-voltage, high-frequency, pulse-width modulated (PWM) boost converter developed by Microchip Technology, a leading provider of microcontroller, mixed-signal, analog, and Flash-IP solutions. This versatile integrated circuit (IC) is designed to drive power LEDs, charge batteries for backup power systems, and convert cell battery voltage to a higher level for a variety of applications.

Encased in an MSOP-8 (Microchip's space-saving, 8-lead Plastic Small Outline Package), the MCP1650R-E/MS is a compact solution ideal for portable electronic devices where space and power efficiency are critical. It operates with an input voltage range of 2.0V to 5.5V, making it suitable for products powered by multiple cell batteries or a single lithium-ion cell.

The MCP1650R-E/MS features a wide range of capabilities that make it a versatile choice for designers. It offers a high switching frequency of up to 1MHz, which allows for the use of smaller, more cost-effective inductors and capacitors, leading to a reduction in overall solution size and cost. Additionally, its high output voltage capability of up to 34V makes it suitable for driving series strings of LEDs, which require higher voltages for operation.

With its integrated low-side switch, the MCP1650R-E/MS can deliver output currents sufficient for many applications without the need for external FETs, simplifying design and reducing component count. Furthermore, the device includes safety features such as thermal shutdown, under-voltage lockout, and overcurrent protection, enhancing the reliability and longevity of the end product.

The MCP1650R-E/MS is also designed with flexibility in mind, providing options for external compensation, which allows designers to tailor the performance of the converter to meet specific application requirements. This flexibility, combined with its small footprint and high-efficiency operation, makes the MCP1650R-E/MS an excellent choice for a wide range of portable and fixed electronics, including LED lighting, battery chargers, and power backup systems.
