illustrate
The LM2830 regulator is a monolithic, high-frequency, PWM step-down DC/DC converter in a 5-pin SOT23 package and a 6-pin LLP package. It offers all the positive features, providing fast transient response and precise adjustment of local DC/DC conversion with minimal PCB area. With minimal external components, the LM2830 is easy to use. Capable of driving an internal 1.0A 130mΩ PMOS load switch using state-of-the-art equipment, the best power density technology of the state-of-the-art 0.5 micron BiCMOS process is available. World-class control circuitry achieves chip multiples to a low 30ns to support very high output voltages that are reduced to a minimum of 0.6V over the entire conversion 3V to 5.5V input operating voltage range. When the switching frequency is internally set to 1.6 MHz or 3.0 MHz, very small surface mount inductors and chip capacitors are allowed. Even at high operating frequencies, efficiencies of up to 93% are easily achievable. External shutdown is included, consisting of an ultra-low current with independent 30 nA. The LM2830 adopts functions such as current mode control and internal compensation, and is highly stable in a wide range of operating conditions. Other features include internal soft-start circuitry to reduce inrush current, pulse pass pulse current limiting, thermal shutdown, and overvoltage protection output.
