Switching Mode Power Supply Design with 900V Switching Regulator

  MP110 is a monolithic regulator with programmable pulse width modulation (PWM) controller, 900V power MOSFET and high voltage current source in one chip. MP110 can be configured as Buck converter...

How to Successfully Apply Low Dropout Regulators

A low dropout (LDO) regulator is capable of maintaining its specified output voltage over a wide range of load currents and input voltages, down to a very small difference between...

Fixed DC/DC Regulator Output Margining Using Digitally Controlled Potentiometer

Many applications using a DC/DC regulator are implemented with a resistor divider in the feedback path to set up Vout. However, for some high end applications, the voltage needs to...

Circuit Guards Amplifier Outputs Against Overvoltage

A universal requirement for automotive electronics is that any device with direct connections to the wiring harness must be able to withstand shorts to the battery voltage. Though brutal, this...

Minimizing the SET-related effects on the output of a voltage linear regulator

This application note deals with the effects of SET (single event transient) on the RHFL4913A low-drop linear regulator. After a short description of the phenomenon, some solutions for coping with...

Principles and Applications of the ICL7660 CMOS Voltage Converter

This application note describes a device originally designed to solve the specific problem of needing a negative supply when only a positive supply is available. This is very common, and...
