ADP3088 is a high-frequency, non-synchronous PWM step-down DC-DC regulator with an integrated 1A power switch in a space-saving MSOP8 package. It provides high efficiency, excellent dynamic response, and is very simple to use. The ADP3088’s 1MHz switching frequency allows for small, inexpensive external components, and the 1A output current makes it ideal for portable computers and other digital products.
The ADP3088 is a 1 MHz, 750 mA buck regulator featuring automatic switching to power-saving mode at light loads and fully integrated soft start. It operates in current-mode control under heavy loads and pulse-skipping mode for efficiency at lighter loads.
Designed for portable applications such as PDAs and notebook computers, the device supports output voltages from 1.25 V to 10.5 V with an input range of 2.5 V to 11 V. It is housed in a space-saving MSOP-8 package.
