General Description
The TS34063A is a monolithic switching regulator and subsystem intended for use as DC to DC converter. It contains an
internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active peak current limit
circuit, drive and a high current output switch.
The TS34063A is specifically designed to be incorporated in step-up, step-down and voltage inverting converter
applications.
The TS34063A is offered in SOP-8 and DIP-8 package.

Terms and Definitions
z Vsat = Saturation Voltage of the output switcDha. taSheet4U.com
z Vf = Forward Voltage drop of the rectifier.
The following power supply characteristics must be chosen:
z Vin= Normal input voltage
z Vout: Desied Output voltage, |Vout| =1.25 (1+R2 / R1)
z Iout : Desired output current.
z fmin : Minimum desired output switching frequency at the selected values for Vin and Io.
z Vripple(p-p): Desired peak-to-peak output ripple voltage. in practice, the calculated capacitor value will need to be
increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value
since it will directly affect the line and load regulation.
