HID Lighting Solutions

Buck Stage
IRS2117: single high side driver, that allows an easy single drive (1 switch).
IRS21844: thanks to its programmable dead time as well as high current capability (1,5A), the IRS21844 eases the design of a synchronized buck (2 switches)

Full bridge
IRS2453D: a self-oscillating full brideg driver with 50% duty cycle, that replaces 2x IRS2153D: two synchronized half-bridge drivers, used in a full bridge configuration. If the control circuitry provides the PWM signals, one of IR’s robust high and low side or half-bridge drivers like IRS2101, IRS2109, IRS2104, IRS2308 can also be used, depending on drive current capabilities as well as topology.
