1.5A Buck/Boost/Inverting DC-DC Regulator
off time at frequencies above 30KHz, and is magnified at high temperatures. This condition does not occur with a Darlington
configuration, since the output switch cannot saturate. If a non-Darlington configuration is used, the following output drive
condition is recommended.
Forced ß of output switch =
I _C Output
≥ 10
I_C Driver − 7mA∗
* The 100Ω resistor in the emitter of the driver device requires about 7.0mA before the output switch conducts.
