Analog Devices ADP1610

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.

FEATURES

Fully integrated 1.2 A , 0.2 Ω, power switch Pin-selectable 700 kHz or 1.2 MHz PWM frequency 92% efficiency Adjustable output voltage up to 12 V 3% output regulation accuracy Adjustable soft start Input undervoltage lockout MSOP 8-lead package

GENERAL DESCRIPTION

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.
