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
