Soft start datasueet constant. A capacitor is connected. This capacitor also determines the. High level output voltage. Low level output voltage. DC open loop gain. The L is a monolithic stepdown switching regu. The load current is sensed by an internal metal. The regulation loop consists of a sawtooth oscilla.

An error signal is produced by comparing the. This error signal is then compared with the sawtooth. The output stage is thus re-enabled and the output. The gain and frequency stability of the loop can be. If the overload condition is still present the limiter.

Closing the loop directly gives an output. The average short circuit current is limited. Higher voltages are obtained by. The thermal overload circuit dis. Output overcurrents at switch on are prevented by. C and has hysteresis to.

The error amplifier output is. Test and application circuit Powerdip. V i rdip vs. Fi gu re R2 see test circuit. Effici en c y vs. A suggestion how to synchronize a negative output. Preregulator for distributed supplies.


In multiple datwsheet several. Ls can be synchronized as shown. The Rth-j-amb of the L can be reduced by. C and the soldering time must not be longer.
