The LM2832 regulator is a monolithic, high frequency, PWM
step-down DC/DC converter in a 6 Pin LLP and a 8 Pin
eMSOP 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 μm 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 LM2832 utilizes 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 inrush
current, pulse-by-pulse current limit, thermal shutdown, and
output over-voltage protection.
