The ADP1610 is a dc-to-dc step-up switching converter with an integrated 1.2 A， 0.2 Ω power switch capable of providing an output voltage as high as 12 V. With a package height of less than 1.1 mm， the ADP1610 is optimal for space-constrained applications such as portable devices or thin film transistor （TFT） liquid crystal displays （LCDs）。 The ADP1610 operates in pulse-width modulation （PWM） current mode with up to 92% efficiency. Adjustable soft start prevents inrush currents at startup. The pin-selectable switching frequency and PWM current mode architecture allow excellent transient response， easy noise filtering， and the use of small， cost-saving external inductors and capacitors. The ADP1610 is offered in the RoHS compliant 8-lead MSOP and operates over the temperature range of ?40°C to +85°C.
