The wide range of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, noise and efficiency. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Features n Input power from 2. Both parts utilize a fixed- frequency, voltage-mode, PWM control architecture and the switching frequency is adjustable from 50kHz to 2MHz by adjusting the value of an external resistor.

LM operate from a low-current 5V bias and can convert. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment.

Datashret Offset TO Z. Electrical specifications do not apply when operating the device. Home – IC Supply – Link. Electrical specifications do not apply when operating the device outside of its stated operating conditions. The LM employs output over-voltage and under- voltage latch-off. V O Output Voltage. Power up and down. Output over-voltage and under-voltage flag LM Both parts utilize a fixed. They are intended to control currents of 0.

Required to Maintain Line Regulation. Physical Dimensions inches millimeters unless otherwise noted Continued. The adap- tive, non-overlapping MOSFET dayasheet and high-side bootstrap structure helps to further maximize efficiency. Current limit is achieved by monitoring the voltage drop across lj78l on- resistance of the low-side MOSFET, which enhances low duty-cycle operation.

Average Output Voltage Tempco. The LM employs output over-voltage and under.
