ICL5101 High-Voltage Resonant Controller IC for LED
Product Brief ICL5101 High-Voltage Resonant Controller IC for LED Driver The ICL5101 integrates a half-bridge controller with a PFC stage in a single package. The high level of integration assures a low count of external components, enabling small Key Features form factor designs ideal for compact power supplies in lighting applications, such as LED driver. Universal AC and DC input Combined PFC and half-bridge IC Integrated high-voltage gate driver The PFC stage operates in CrCM and DCM mode, supporting stable operation at low load conditions down to 0.1% of the nominal power. The half-bridge resonant stage – typically in LLC topology – provides high- and low-side gate drive function for discrete MOSFETs rated up to 650V. Its non-overlap dead time is adaptive from 500ns ... 1.0µs. All operation parameters of the IC are adjustable by simple resistors, this being the ideal choice for cheap and reliable configuration. A comprehensive set of protection features incl. an adjustable external over temperature protection and capacitive load protection ensures the detection of fault conditions to increase the system safety. High efficiency up to 95% Short startup time < 200ms Key Benefits High level of integration resulting in a low external component count and a cost All operation parameters are adjustable with simple resistors to allow simple configuration Stable low load operation mode Comprehensive protection modes Applications Indoor and outdoor high-power LED lighting High-bay and low-bay lighting Street lighting Parking garages and area lighting Office panel lighting Product Summary Type Description Ordering Code ICL5101 Resonant controller with PFC SP001213622 www.infineon.com Power factor > 99%, THD < 10% Product Brief ICL5101 Resonant Controller IC with PFC Typical Application Schematic D1 PFCZCD C1 R6 Q1 R1 PFCGD C4 R2 C5 HSGND ICL5101 PFCVS LSGD PFCCS LSCS R7 D6 R15 ϑR11 R8 L4_3 D8 L4_2 C12 L4_4 D9 R20 R23 D4 R19 C8 D7 R21 R22 R17 C6 L4_1 C11 Q3 R14 R16 C3 C9 L3 C7 R4 C2 Q2 R13 HSGD HSVCC n.a.
