DESCRIPTION
The iP1827 iPOWIR
and highly efficient DC/DC regulator. The onboard PWM
controller and MOSFETs make iP1827 a space‐efficient
solution, providing accurate power delivery for low output
voltage and high current applications.
iP1827 is a versatile regulator which offers programmability
of switching frequency and current limit while operating in
wide input and output voltage range.
The switching frequency is programmable from 250kHz to
1.5MHz for an optimum solution.
It also features important protection functions, such as
Pre‐Bias startup, hiccup current limit and thermal
shutdown to give required system level security in the
event of fault conditions.
