CR5541/CR5541H High Voltage Green Mode Power Switch GENERAL DESCRIPTION CR5541/CR5541H is a highly intergrated current mode PWM power switch. It built in patent High voltage startup, optimized for high performance, exhibit extra low standby power consumption (<50mW). PWM switching frenquency at normal operation is internally fixed. At no load or light load condition, It operates in hiccup mode to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved. Less than 50mW standby power consumption and very high conversion efficiency is thus achieved. Patent high voltage startup is implemented in CR5541/CR5541H, which features with short startup time and extra low standby current. CR5541/CR5541H offers rich protection with auto-recovery including Cycle-by Cycle current limiting (OCP), over load protection (OLP), VDD under voltage lockout (UVLO), and over temperature protection (OTP), VDD over voltage protection (OVP). Excellent EMI performance is achi...
