The LMR10510 regulator is a monolithic, high
frequency, PWM step-down DC/DC converter in a 5
pin SOT-23 and a 6 Pin WSON 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 LMR10510 is
easy to use. The ability to drive 1.0A loads with an
internal 130 m ? PMOS switch 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. The
LMR10510 is a constant frequency PWM buck
regulator IC that delivers a 1.0A load current. The
regulator has a preset switching frequency of 1.6MHz
APPLICATIONS
or 3.0MHz. This high frequency allows the LMR10510
to operate with small surface mount capacitors and

inductors, resulting in a DC/DC converter that
requires a minimum amount of board space. The
LMR10510 is internally compensated, so it is simple
to use and requires few external components. 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 LMR10510 utilizes current-mode control and
internal compensation to provide high-performance
regulation over a wide range of operating conditions.
PERFORMANCE BENEFITS
Additional features include internal soft-start circuitry

Extremely easy to use
Tiny overall solution reduces system cost
to reduce inrush current, pulse-by-pulse current limit,
thermal shutdown, and output over-voltage
protection.
