... PWM is low driven high and DH is driven low. This prevents the output of the con- verter from rising before a valid PWM signal is applied. When EN is low, the MAX8552 is in shutdown mode and the total input current is reduced to less than 1µA for power-sensitive applications. In shutdown mode, both DH and DL are held low ...
