General Description

The PAM2306 is a dual step-down current-mode, DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2306 provides a power-saving PulseSkipping Modulation (PSM) mode to reduce quiescent current under light load operation.
