BASIC APPLICATION

Figure 1 : iP1827 Basic Application Circuit

DESCRIPTION

The iP1827 iPOWIR

TM is an easy‐to‐use, fully integrated

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.

APPLICATIONS

 Server Application

 Netcom Applications

 Embedded Telecom Systems

 Distributed Point of Load Power Architectures
