www.ti.com SNVS455A – AUGUST 2006 – REVISED APRIL 2013 LM2832 High Frequency 2.0A Load -Step-Down DC-DC Regulator
Check for Samples: LM2832 FEATURES DESCRIPTION The LM2832 regulator is a monolithic, high frequency,
PWM step-down DC/DC converter in a 6 Pin WSON
and a 8 Pin eMSOP-PowerPAD package. It provides
all the active functions to provide local DC/DC
conversion with fast transient response and accurate
regulation in the smallest possible PCB area. With a
minimum of external components, the LM2832 is
easy to use. The ability to drive 2.0A loads with an
internal 150 mΩ PMOS switch using state-of-the-art
0.5 Вµm BiCMOS technology results in the best power
density available. The world-class control circuitry
allows on-times as low as 30ns, thus supporting
exceptionally high frequency conversion over the
entire 3V to 5.5V input operating range down to the
minimum output voltage of 0.6V. Switching frequency
is internally set to 550 kHz, 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 stand-by current of 30 nA. The …
