OCP8172

WWW.ORIENT-CHIP.COM OCP8172 One-Channel High Power LED Controller ◼ General Description The OCP8172 is a high power LED driver, non-synchronous boost controller. The OCP8172 can be used for the LED backlight in LCD panels. It is designed for current mode control power converters that require a single drive output, such as boost LED driver and SEPIC topologies. The OCP8172 is suitable for topologies which require a ground source N-channel FET including boost, SEPIC and various LED driver applications. The device features include programmable oscillator frequency, power MOSFET over-current protection (OCP), over-voltage protection (OVP), under-voltage lock-out (UVLO), output to ground short-circuit protection (SCP), LED-short protection and Over Temperature protection (OTP). A soft-start feature is provided to minimize in-rush current during start-up. The OCP8172 is available in SOP-14L and SSOP-10L package, and it is RoHS compliant. Operating temperature range of the OCP8172 is fro...
