Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions.

Note 2: For Tj > 100 C, the Emitter pin voltage should not be driven more than 0.6V below ground (see Application Information).

Note 3: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the TO-99 package must be derated at 150 C/W, junction to ambient, or 45 C/W junction to case. The device in the 8-pin DIP must be derated at 95 C/W, junction to ambient. The device in the surface-mount package must be derated at 150 C/W, junction-to-ambient.

Note 4: Human body model, 1.5k Ohm in series with 100pF.

The 6371 is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost, and inverting configurations. The 6371 features a unique comparator input stage which not only has separate pins for both the inverting and non-inverting inputs, but also provides an internal 1.0V reference to each input,thereby simplifying circuit design and p.c. board layout. The output can switch up to 750mA and has output pins for its collector and emitter to promote design flexibility. An external current limit terminal may be referenced to either the ground or the Vin terminal, depending upon the application. In addition, the 6371 has an on board oscillator, which sets the switching frequency with a single external capacitor from < 1Hz to 100kHz (typical).

The 6371 is an improved version of the LM1578, offering higher maximum ratings for the total supply voltage and output transistor emitter and collector voltages.
