ADP1612/ADP1613应用电路(650 kHz /1.3 MHz Step-Up PWM DC-to-DC Switching Converter)

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.
