General Description
TS34063 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 TS34063 is specifically designed to be
incorporated in step-up, step-down and voltage inverting converter applications. TS34063 is offered in SOP-8 and
DIP-8 package

Notes1: Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient
temperature as possible
Note 2: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents
(<=300mA) and high driver currents (>=30mA), it may take up to 2uS for it to come out of saturation. This
condition will shorten the off time at frequencies >= 30KHz, and is magnified at high temperature. This
condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a non-
darlington configuration is used, the following output drive condition is recommended: Forced Bata of
output switch: Ic output / (Ic driver – 7mA*) >= 10
* The 100ohm resistor in the emitter of the driver divide requires about 7mA before the output switch
conducts.
