The PAM2303 is a 3A step-down DC-DC converter. It operates in two
different modes: PSM and PWM modes. At light load, it
automactically enters into the PSM mode to improve efficiency. At
heavy load, the constant frequency PWM control performs excellent
stability and transient response. No external compensation
components are required.
The PAM2303 supports a range of input voltages from 2.7V to 5.5V.
The output voltage is adjustable from 0.6V to the input voltage. The
PAM2303 employs internal power switch and synchronous rectifier to
minimize external part count and realize high efficiency. During
shutdown, the input is disconnected from the output and the
shutdown current is less than 1μA. Other key features include over temperature
and short circuit protection, and under-voltage lockout to
prevent deep battery discharge.
The PAM2303 delivers 3A maximum output current while consuming
only 42μA of no-load quiescent current. Ultra-Low RDS(ON) integrated
MOSFETs and 100% duty cycle operation make the PAM2303 an
ideal choice for high-output voltage, high-current applications which
require a low dropout threshold.
The PAM2303 is available in SOP-8(EP), DFN3X3-10 and QFN3X3-
