| 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.
