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 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.
