The ADP1612/ADP1613 are step-up dc-to-dc switching converters with an integrated power switch capable of providing an output voltage as high as 20 V. With a package height of less than 1.1 mm， the ADP1612/ADP1613 are optimal for spaceconstrained applications such as portable devices or thin film transistor （TFT） liquid crystal displays （LCDs）。 The ADP1612/ADP1613 operate in current mode pulse-width modulation （PWM） with up to 94% efficiency. Adjustable soft start prevents inrush currents when the part is enabled. The pin-selectable switching frequency and PWM current-mode architecture allow for excellent transient response， easy noise filtering， and the use of small， cost-saving external inductors and capacitors. Other key features include undervoltage lockout （UVLO）， thermal shutdown （TSD）， and logic controlled enable. The ADP1612/ADP1613 are available in the lead-free 8-lead MSOP.
