The LM2831Y from Texas Instruments is a monolithic, high-frequency, PWM step-down DC-DC converter. It is designed to provide local DC-DC conversion with fast transient response and accurate regulation in a compact PCB area.
This regulator supports an output current of up to 1.5A and features an internal 130mΩ PMOS switch. The input voltage range is from 3V to 5.5V, with an output voltage range of 0.6V to 4.5V. The device operates at high switching frequencies, with specific frequencies varying by model (e.g., 0.55 MHz for LM2831Y).
Key internal features include a 0.6V, 2% internal voltage reference, internal soft-start, current mode PWM operation, thermal shutdown, and overvoltage protection. The operating temperature range is -40°C to 125°C.
The LM2831Y is housed in a space-saving 5-pin SOT-23 package, making it suitable for applications where PCB area is limited. It requires a minimum of external components for ease of use.
