General Description

The uP1542 is a pact synchronous-rectified buck controller specifically designed to operate from 5V or 12V supply voltage and to deliver high quality output voltage as low as 0.6V for uP1542S/U (linear OCP).

The uP1542 adopts constant frequency, voltage mode control scheme, featuring easy-to-use, low external ponent count, and fast transient response.

Fixed 300kHz operation provides an optimal level of integration to reduce size and cost of the power supply.

Key Features

  • include internal soft start, over/under voltage protection, over current protection and shutdown function. With aforementioned functions, this part provides customers a compact, high efficiency, well-protected and cost-effective solutions. This part is available in PSOP8L and WDFN2x2-8L package.
