General Description
   The PAM2319 is a dual step-down current-mode, DC-DC converter. At heavy load, the constantfrequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2319 provides a power-saving Pulse-Skipping Modulation (PSM) mode to reduce quiescent current under light load operation.
