The STMicroelectronics PM8903ATR is a monolithic switching regulator designed for step-down DC/DC conversion applications. It can deliver up to 3A of output current and features an adjustable output voltage that can be set as low as 0.6V.
This regulator operates at a high switching frequency of 1.1MHz, enabling the use of smaller external components and contributing to a compact solution. The device is housed in a 16-VFQFPN package with a 3x3mm footprint and 1mm height, suitable for surface mount applications.
Key electrical specifications include a minimum input voltage of 2.8V, a nominal input voltage of 3.3V, and a maximum input voltage of 6V. The PM8903ATR is designed for voltage-mode control with pulse width modulation.
Environmental compliance includes RoHS3 compliance and an MSL 1 rating. The component is available for RFQ, with pricing and lead times provided upon request.
