current mode, constant frequency pulse-width modulation (PWM)
control scheme for excellent stability and transient response.
The input voltage range of the
output voltage of the
input voltage (V
output voltage options: 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, and 1.0 V.

The
and N-channel internal MOSFETs to maximize efficiency and
minimize external component count. The 100% duty cycle
operation allows low dropout voltage at 4 A output current.
The high, 1.2 MHz PWM switching frequency allows the use of
small external components, and the SYNC input enables multiple
ICs to synchronize out of phase to reduce ripple and eliminate
beat frequencies.
Other key features of the
(UVLO), integrated soft start to limit inrush current at startup,
overvoltage protection (OVP), overcurrent protection (OCP),
and thermal shutdown.
