SC4505EVB規(guī)格書詳情
Description
The SC4505 is a high-frequency PWM current-mode step up switching regulator with an integrated 2A power transistor. Its high switching frequency (1MHz) allows the use of tiny surface-mount external passive components. The internal switch is rated at 36V which makes the converter ideal for multiple LED series operation with optimal current matching. Two programmable independent current source structure allows dual panel LED backlight and flash operation.
Features
?Two independent current sources for dual LED strandswith optimal current/light matching. acklight up to75mA, Flash up to 125mA
?Wide input range from 2.6V to 12V
Adaptive output voltage up to 28V with OVP protection against open circuit conditions
Low shutdown current (<1μA )
Internal Flash/Torch mode with flash timeout to protect LEDs
1MHz Fixed Frequency Current-Mode Control
Internal 2A current limit for driving large numbers of LEDs
Supports PWM Dimming from 50Hz to 50kHz
Internal undervoltage lockout
Small, low profile, thermally enhanced 16-MLPQ package is fully WEEE and RoHS compliant
