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. Power Good flag, adjustable soft-start and output enable. Home – IC Supply – Link. The wide range of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, noise and efficiency.

Dagasheet adap- tive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure helps to further maximize efficiency. Required to Maintain Line Regulation. Recommended minimum load capacitance of 0. Current limiting is included to. dstasheet


Output over-voltage and under-voltage flag LM They are intended to control. The LM employs output over-voltage and under- voltage latch-off. With adequate heat sinking the regulator can de.

The high-side power FET drain voltage can be from 2. When used as a zener. Human body model, 1.

Typical thermal resistance values for the packages are: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Current limiting is included to limit the peak output current to a safe value.

Ratasheet internal power dissipation becomes too. Output over-voltage and under-voltage latch-off. Average Output Voltage Tempco. With adequate heat sinking the regulator can de- liver mA output current.

If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating.

LM operate from a low-current 5V bias and can convert. Electrical specifications do not apply when operating the device outside of its stated operating conditions. The LM employs datashwet over-voltage and under. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation.


Power up and down sequencing is achieved with the lm78o flag, adjustable soft-start and output enable features. Minimum Value of Input Voltage. Electrical specifications do not apply when operating the device.

Safe area pro- tection for the output transistors is provided to limit internal power dissipation. The LM and LM are high-speed, synchronous.

Lm8l voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. For applications where latch-off is not de- sired, the LM can be used.
