描述 Description
AS1142 is simple, easy to use, 2A synchronous step down(Buck) convertor in TSOT23-6L package, with high efficiency and fast transient response. AS1142 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. AS1142 adopts the active constant on time PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it keeps in constant frequency of 500kHz under heavy load conditions to minimize the size of inductor and capacitor. Fault conditions also include cycle-by-cycle current limit, output under voltage protection, output over current protection, output short-circuit protection and thermal shutdown
