General Description
The TS3063 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 TS3063 is specifically designed to be incorporated in step-up, step-down and voltage inverting converter
applications. The TS3063 is offered in SOP-8 and MSOP-8 package

800mA/180kHz Dc to Dc Converter Controller
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 nonDarlington 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.
