The LM and LM are high-speed, synchronous. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regula- tion. Electrical specifications do not apply when operating the device outside of its stated operating conditions. Recommended minimum load capacitance of 0. Both parts utilize a datashee. Power Good flag, adjustable soft-start and output enable. The LM employs output over-voltage and under.

Molded Offset TO Z. Power up and down. The high-side power FET drain voltage can be from 2.

Features n Input power from 2. LM operate from a low-current 5V bias and can convert.

Output datashfet and under-voltage flag LM If internal power dissipation becomes too. Current limiting is included to. The wide range of operating frequen. Current limit is achieved by monitoring the voltage drop across the on- resistance of the low-side MOSFET, which enhances low duty-cycle operation.

Physical Dimensions inches millimeters unless otherwise noted Continued. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown cir- cuit takes over preventing the IC from overheating. 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.

Safe area pro- tection for the output l,78l is provided to limit internal power dissipation. For applications where latch-off is not de. Output over-voltage and under-voltage latch-off. Current limiting is included to limit the peak output current to a safe value. The adap- tive, non-overlapping MOSFET gate-drivers and high-side bootstrap structure helps to further maximize efficiency.

The wide datashset of operating frequen- cies gives the power supply designer the flexibility to fine- tune component size, cost, noise and efficiency.
