National Semiconductor recently introduced a high-voltage, monolithic two-switch forward DC-DC regulator for power supply designs in telecommunication, automotive and industrial applications. The highly integrated LM5015 features an ultra-wide input voltage range from 4,25 V to 75 V and maximum switching frequency of 750 kHz. The IC enables easy implementation of either isolated or non-isolated DC-DC converters using a minimum of external components.
Offered in a small TSSOP package, the LM5015 integrates two 75 V N-Channel MOSFET switches for a reduced system component count and very small solution size. The two-switch forward architecture reduces system losses and noise.
The regulator features all of the functions necessary to implement efficient two-switch forward and two-switch flyback power converters with a minimum of external components. It integrates high-side and low-side 75 V N-Channel MOSFETs with a minimum 1 A peak current limit. The voltage across the MOSFETs employed in the two-switch topology is clamped to the input voltage, allowing the input voltage range to approach the rating of the MOSFETs. The regulator control method is based on current-mode control, providing inherent ease-of-loop compensation and line feed-forward for superior rejection of input transients.
The operating frequency of the LM5015 is set with a single resistor and the oscillator can also be synchronised to an external clock. Additional protection features include cycle-by-cycle current limiting, thermal shutdown, under-voltage lockout and remote shutdown capability. The LM5015 is offered in a 14-pin TSSOP package featuring an exposed die attach pad to enhance thermal dissipation.
