uP1708 - 26V High-Efficiency Synchronous-Rectified Buck Converter

Description

The uP1708 is a high efficiency synchronous-rectified buck converter with internal power switches.

Fixed 300kHz PWM operation allows possible smallest output ripple and external component size.

Features

  • fast transient response to step load change. The converter supports PSM mode operation at light load condition, thus yields very high efficiency over a wide range of load current. With integrated high voltage MOSFET, the uP1708 is capable of delivering 5A output current over a wide input range from 5V to 26V. The output voltage is adjustable from 0.8V to 80% of VIN by a voltage divider. Other features include internal soft-start, chip enable, under voltage, over temperature and over current prot.

uP1708 300KHz, 5A, 26V High-Efficiency Synchronous-Rectified Buck Converter General Description The uP1708 is a high efficiency synchronous-rectified buck converter with internal power switches. Fixed 300kHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1708 is ideally suitable for applications where PCB area is especially concerned. Designed with slope-compensated current mode control, the uP1708 features fast transient response to step load change. The converter supports PSM mode operation at light load condition, thus yields very high efficiency over a wide range of load current.
