Description
The LM2830 regulator is a monolithic, highfrequency, PWM step-down DC-DC converter in a 5pin SOT-23 and a 6-Pin WSON package. The device provides all the active functions to provide local DCDC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components, the LM2830 regulator is easy to use. The ability to drive 1.0-A loads with an internal 130-mΩ PMOS switch using state-of-the-art 0.5-µm BiCMOS technology results in the best power density available. The worldclass control circuitry allows on-times as low as 30 ns, thus supporting exceptionally high frequency conversion over the entire 3-V to 5.5-V input operating range down to the minimum output voltage of 0.6 V. Switching frequency is internally set to 1.6 MHz, or 3.0 MHz, allowing the use of extremely small surface-mount inductors and chip capacitors. Even though the operating frequency is high, efficiencies up to 93% are easy to achieve. External shutdown is included, featuring an ultra-low standby current of 30 nA. The LM2830 regulator uses current-mode control and internal compensation to provide highperformance regulation over a wide range of operating conditions. Additional features include internal soft-start circuitry to reduce inrush current, pulse-by-pulse current limit, thermal shutdown, and output overvoltage protection.
