STMICROELECTRONICS STBB3JR 直流-直流开关降压-升压稳压器, 可调, 1.8V-5.5V输入, 1.2V-5.5V输出, 2A输出, Flip Chip-20
The is a fixed frequency high efficiency buck-boost DC-to-DC Converter which provides output voltage from 1.2 to 5.5V starting from input voltage from 1.8 to 5.5V. 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-RDSon 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.
