illustrate

The LM2738 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in an 8-pin LLP or 8-pin eMSOP package. It provides all local DC/DC conversion activities with fast transient response and accurate regulation of minimal PCB area.

With minimal external components, the LM2738 is easy to use. Capable of driving an internal 250mΩnmos 1.5A load switch using the best power density provides state-of-the-art equipment with the results of state-of-the-art 0.5 micron BiCMOS technology. The switching frequency is internally set to 550kHz (LM2738Y) or 1.6MHz (LM2738X), allowing the use of very small surface mount inductors and chip capacitors. Even at very high operating frequencies, efficiencies of up to 90% are easily achievable. External enable is included and has an ultra-low standby current of 400nA. The LM2738 adopts functions such as current mode control and internal compensation, and is highly stable in a wide range of business conditions. Other features include internal soft-start circuitry to reduce inrush current, cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection.
