Overview

Adjustable High Output Voltage High Efficiency Step-Up DC/DC Converter CE9908 Adjustable High Output Voltage High Efficiency Step-Up DC/DC Converter CE9908 INTRODUCTION The CE9908 is a CMOS step-up switching DC/DC converter, which allows the duty ratio to be automatically switched according to the load (light load: 50%, high output current: 75%), enabling products with a low ripple over a wide range, high efficiency, and high output current.

With the CE9908, a step-up switching DC/DC converter can be configured by using an external coil, capacitor, diode and NMOS.

This feature, along with the mini package and low current consumption, makes the CE9908 ideal for applications such as the power supply unit of portable equipment.
