Page 1
... General Description The TS34063A is a monolithic switching regulator and subsystem intended for use 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 ...

... Darlington configuration, since the output switch cannot saturate non-Darlington configuration is used, the following output drive condition is recommended: Forced Bata of output switch: Ic output / (Ic driver – 7mA*) > The 100ohm resistor in the emitter of the driver divide requires about 7mA before the output switch conducts. TS34063A ...

... 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. TS34063A Step Down Vin ...
