昱灿电子 .szyucan.  Application Note: SY7215 High Efficiency, 15A Synchronous Step Up Regulator with Accurate Output Current Limit General Description SY7215 develops a high efficiency synchronous Boost regulator with programmable output current limit. The device adopts adaptive constant off time and current mode control. The integrated low RDS(ON) switches minimize the conduction loss. SY7215 Features cycle by cycle peak current limit, output short circuit protection and true shutdown. The device also provides enable control and power good indicator for system sequence control. Low output voltage ripple and small external inductor and capacitor size are achieved with programmable pseudo-constant frequency.
