Description
The DPA-Switch™ IC family is a highly integrated solution for
DC-DC conversion applications with 16‑75 VDC input.
DPA-Switch uses the same proven topology as TOPSwitch™,
cost effectively integrating a power MOSFET, PWM control, fault
protection and other control circuitry onto a single CMOS chip.
High performance features are enabled with three user
configurable pins. Hysteretic thermal shutdown is also provided.
In addition, all critical parameters (i.e. current limit, frequency,
PWM gain) have tight temperature and absolute tolerance, to
simplify design and reduce system cost.
