UD24121中文资料1.2A, 24V, 1.4MHz STEP-DOWN CONVERTER数据手册UTC规格书
UD24121规格书详情
描述 Description
The UTC UD24121 is a monolithic step-down switching mode converter with a built-in power MOSFET. It regulates input voltages from 4.5V to 24V down to an output voltage as low as 0.81V, and supplies up to 1.2A of load current. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The UTC UD24121 requires a minimum number of readily available standard external components. APPLICATIONS * Distributed Power Systems * Battery Charger * Pre-Regulator for Linear Regulators * WLED Drivers
