Product Summary
The mb3883pv is a 6-channel step-up/step-down DC/DC converter IC using pulse width modulation (PWM) and synchronous rectification, designed for low voltage, high efficiency, and compact size. The mb3883pv is ideal for up conversion, down conversion, and up/down conversion (using a step-up/step-down Zeta system with free input and output settings). The mb3883pv can operate at low voltage levels, and has a wide supply voltage range from 1.7 V to 9 V. The mb3883pv is available in two packages, an LQFP-48P or a leadless BCC-48P formed with a contact electrode pad only. This is an ideal power supply for high-performance portable devices such as digital still cameras.
