The Texas Instruments LM2640MTC-ADJ/NOPB is a dual step-down switching power supply controller designed for battery-powered equipment like notebook personal computers. It offers a wide input voltage range from 5.5V to 30V and operates at a fixed 200 kHz switching frequency, with synchronization capability up to 400 kHz.
Key electrical specifications include adjustable output voltages from 2.2V to 6V, high efficiency up to 96%, and precise load and line regulation. The controller also integrates a 5V, 50 mA linear regulator output and a 2.5V precision reference output. It supports programmable soft-start for each controller and includes undervoltage lockout and shutdown protection features.
Packaged in a 28-TSSOP surface mount configuration, the LM2640MTC-ADJ/NOPB operates within a temperature range of 0°C to 125°C. Its design facilitates ultra-efficient power conversion over a wide load current range, with an optional pulse-skipping mode that can be disabled for fixed-frequency operation.
This component is suitable for applications requiring dual adjustable step-down power supply control, offering flexibility and efficiency in power management solutions.
