描述 Description

Push-Pull PWM ControllerThe IPS201A and IPS201B are low-voltage PWM controllers that contains all the features needed to implement Push-Pull, Half-Bridge, and Full-Bridge topologies. They are used in switch mode power supplies to provide pulse width modulation to a pair of high voltage/high current MOSFETs. Both devices include an oscillator, error amplifier, current sensing, and a regulated voltage reference output.The IPS201 is presented in voltage mode or current mode versions. Both the frequency and the dead time are set by the user by choosing the appropriate external RC components.FeaturesShunt regulator VCC supply for wide input voltage rangeTwo output driversExternal resistor/capacitor set the adjustable operating frequency and dead time5V output and oscillator sawtooth are available to provide slope compensationAvailable in versions utilizing voltage mode (IPS201A) or current mode control (IPS201B)Voltage mode is available with two different overcurrent sense thresholds (60mV and 700mV)Industrial temperature range (-40oC to +85oC) standardApplicationsAC / DC power suppliesDC / DC power suppliesFlourescent lamp driversDC / AC inverters
