产品概述

描述

The STBB3J is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 5.5 V starting from input voltage from 1.8 V to 5.5 V. The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for cell lithium-Ion applications where the output voltage is within the battery voltage range. The low-RDS(on) N-channel and P-channel MOSFET switches are integrated and contribute to achieve high efficiency. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage from either lower power consumption or best dynamic performance.The device also includes soft-start control, thermal shutdown, and current limit. The STBB3J is packaged in Flip Chip 20 bumps with 2.5 x 1.75 mm.
