ADP1611:  20 V,1.2 MHZ STEP-UP DC-TO-DC SWITCHING CONVERTER

Product Description

The ADP1611 is a step-up dc-to-dc switching converter with an integrated 1.2 A, 0.23 Ω power switch capable of providing an output voltage as high as 20 V. With a package height of less than 1.1 mm, the ADP1611 is optimal for space-constrained applications such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs).

The ADP1611 operates in pulse-width modulation (PWM) current mode with up to 90% 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 ADP1611 is offered in the Pb-free 8-lead MSOP and operates over the temperature range of −40°C to +85°C.

Functional Block Diagram for ADP1611

Important: Use the ADP1612 or ADP1613 Instead

The ADP1612 or ADP1613 are recommended for new designs instead of the ADP1611.
- The ADP1612 is a 650 kHz /1.3 MHz step-up PWM DC-to-DC switching converter with 1.4 A current limit.
- The ADP1613 is a 650 kHz /1.3 MHz step-up PWM DC-to-DC switching converter with 2.0 A current limit.
