Microchip Technology MCP1664T-E/OT Product Overview

The MCP1664T-E/OT is a high-voltage, non-synchronous step-up converter from Microchip Technology's expansive portfolio of power management solutions. This compact and efficient device is designed to operate with an input voltage range of 2.0V to 5.5V, making it an ideal choice for battery-powered applications, including 2-cell alkaline or NiMH/NiCd, as well as single-cell Li-Ion or Li-Polymer batteries.

With its integrated 32V N-Channel Power MOSFET, the MCP1664T-E/OT is capable of delivering output voltages up to 32V, which can be adjusted by an external resistor divider. Its high switching frequency of 500 kHz allows for the use of small external components, thereby reducing the overall solution footprint—a crucial benefit for space-constrained applications.

The device features a fixed off-time peak current mode control which simplifies the design and provides an excellent transient response. Additionally, it comes with a range of built-in safety features including over-temperature protection, under-voltage lockout (UVLO), and over-current protection (OCP), ensuring reliable operation under various conditions.

Housed in a tiny 5-pin SOT-23 package, the MCP1664T-E/OT is optimized for portable electronics where size and efficiency are critical. Applications such as LED drivers, power supplies for small OLED displays, and bias voltage generation for sensors or small-scale microcontrollers can significantly benefit from the features of this high-performance boost converter.
