1.2 MHz DC-DC Step-Up Switching Converter

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 that 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 Pb-free 8-lead MSOP and operates over the temperature range of −40°C to +85°C.
