Description
Demonstration circuit DC1198A-A features the
LTM
mode buck-boost µModule
regulate its output voltage from an input voltage above,
below, or equal to the output. The input voltage range
of DC1198A-A is from 4.5V to 20V with a preset output
voltage of 12V. The rated load current is 5A, although
derating is necessary for certain V
conditions. The switching frequency may be synchronized
to an external clock from 200kHz to 400kHz. This PLL
