1.2 MHz DC-DC Step-Up Switching Converter

ADP1610

FEATURES

GENERAL DESCRIPTION

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

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.

APPLICATIONS

TFT LC bias supplies

Portable applications

Industrial/instrumentation equipment

The ADP1610 is offered in the Pb-free 8-lead MSOP and

operates over the temperature range of −40°C to +85°C.
