The Microchip Technology TC105333ECTTR is a versatile step-down (Buck) switching controller. It provides an output current of up to 1A with a typical efficiency of 92%, making it suitable for power-sensitive applications.
This controller operates at a switching frequency of 300kHz, enabling the use of small inductors and reducing overall solution size. It features a low supply current of 57µA typical and a shutdown mode current of less than 0.5µA, further conserving power. The TC105333ECTTR supports input voltages ranging from 2.2V to 10V and is available in a compact 5-Pin SOT-23A package.
Applications for this device include palmtops, portable instruments, positive LCD bias generators, and portable communicators. Its ability to automatically switch between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes enhances efficiency at varying load conditions. The device operates within a temperature range of -40°C to 85°C.
