The LM2653MTCX-ADJ/NOPB from Texas Instruments is a high-efficiency synchronous switching regulator designed for versatile power conversion. It supports an input voltage range of 4V to 14V and provides an adjustable output voltage from 1.5V to 5V, making it suitable for battery-powered applications.
This regulator features a 1.5A output current capability and operates at a fixed 300kHz switching frequency. Synchronous rectification is employed to achieve efficiencies up to 97%. At light loads, it enters a low-power hysteretic or 'sleep' mode to maintain high efficiency, often exceeding 80% even at 15mA loads.
Protection features include thermal shutdown, input undervoltage lockout, adjustable soft-start, cycle-by-cycle current limit, and output overvoltage/undervoltage protection. The device is housed in a 16-TSSOP package and is designed for surface mount applications.
Key electrical specifications include a 0.1Ω switch on-resistance and a 7μA shutdown current. The patented current sensing for current mode control eliminates the need for an external current sense resistor.
