FAIRCHILD SEMICONDUCTOR FAN5331SX 直流-直流开关升压稳压器, 可调, 2.7V-5.5V输入, 2.7V-20V输出, 1A输出, SOT-23-5
The is a general purpose fixed-frequency Boost Converter designed to operate at high switching frequencies in order to minimize switching noise measured at the battery terminal of hand-held communications equipment. Quiescent current in normal mode of operation as well as in shutdown mode is designed to be minimal in order to extend battery life. Normal mode of operation or shutdown mode can be selected by a logic level shutdown circuitry. The low on-resistance of the internal N-channel switch ensures high efficiency and low power dissipation. A cycle-by-cycle current limit circuit keeps the peak current of the switch below a typical value of 1A.
