National Semiconductor has expanded its high power-density regulator line with the LM2830/1/2.
These regulators are monolithic, high-frequency, PWM step-down DC-DC converters. According to the manufacturer, they provide all the active functions necessary for local DC-DC conversion, with fast transient load response and accurate regulation in the smallest possible board area. All three regulators have few external components, making them easy to design with.
The LM2831, in a tiny SOT23-5 (also available in a 6-lead LLP package), offers industry-leading power density by providing a 1,5 A output current while operating at 1,6 MHz or 3 MHz. The 2 A LM2832 in a 6-lead LLP package (also available in 8-pin MSOP), is available at 550 kHz, 1,6 MHz and 3 MHz switching frequencies. The 1 A LM2830 is available with 1,6 MHz and 3 MHz switching frequency options in SOT23-5 and 6-lead LLP packages.
This range of output currents, switching frequencies and packaging options gives designers flexibility in choosing a regulator for conversion from a 3,3 V to 5 V bus to output voltages as low as 0,6 V. This is ideal for point-of-load power requirements in set-top boxes, xDSL cable modems, broadband communications, network cards, computing peripherals and hard disk drives.
External shutdown is included, with an ultra-low standby current of 30 nA. The regulators also use current-mode control and internal compensation to provide high-performance regulation over a wide range of operating conditions. Additional features include internal soft-start circuitry to reduce in-rush current, pulse-by-pulse current limit, thermal shutdown and output over-voltage protection.
