illustrate
The LM2832 regulator is a monolithic, high frequency, PWM step-down DC/DC converter available in 6-pin LLP and 8-pin eMSOP packages. It provides all active functions, provides fast transient response, and precisely adjusts local DC/DC conversion with the smallest possible PCB area. With minimal external components, the LM2832 is easy to use. 150 meters, internal 2.0A load drive capacity PMOS switches use state-of-the-art 0.5 micron BiCMOS process technology to achieve optimal power density. World-class control circuitry allows a time as low as 30ns, allowing very high frequency conversion over the entire 3V frequency with a minimum output voltage range of 0.6V to 5.5V. The switching frequency of 1.6 MHz or 3.0 MHz with an internal setting of 550 kHz allows the use of very small surface mount inductors and capacitors. Even with high operating frequencies, efficiencies as high as 93% are easily achievable. External shutdown is included with an ultra-low standby current of 30 nA. The LM2832 uses current mode control and internal compensation to provide high-performance regulation for 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 output overvoltage protection.
