TMI3252SH2 1MHz 18V 2A Synchronous Step-Down Converter with Force PWM Operation
■The TMI3252SH2 is a high efficiency 1MHz, Constant on-time control mode synchronous step-down DC-DC converter capable of delivering up to 2A current. TMI3252SH2 integrates main switchand synchronous switch with very low R-DS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor size are achieved with 600KHZ switching frequency . It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.
■The TMI3252SH2 requires a minimum number of readily available standard extemal components and is available in a 6-pin SOT23-6 ROHS compliant package.
