DUAL 42V, 2MHz Sync Buck VIN 3.4V to 42V VIN1 VOUT1 @1.5A SW1 LT8616 SW2 VIN2 VOUT2 @2.5A 96% Efficient, 2.5A and 1.5A Outputs, 6.5µA IQ The LT®8616 brings a new level of performance for 42V input monolithic synchronous buck converters by incorporating dual outputs in a FMEA compliant 28-pin package. Channel 1 is capable of delivering 1.5A of continuous output current, while channel 2 can deliver 2.5A, both with outputs as low as 0.8V. Each channel operates 180° out of phase to further reduce input ripple. Burst Mode® operation requires only 6.5µA of quiescent current (both channels on), thereby extending battery life in battery-powered systems. For high step-down ratio applications, the LT8616 bucks from 16V down to 1.5V at a switching frequency of 2MHz, enabling a compact solution footprint. Efficiency with 12VIN to 5VOUT and 3.3VOUT Features • Input Voltage Range: 3.4V to 42V • Dual Outputs: 2.5A and 1.5A • Ultralow Quiescent Current: 6.5µA (Both Channels On) • Low Output Ripple: < 10mVP-P • Adjustable/Synchronizable Frequency: 200kHz to 3MHz • High Step-Down Ratios: 16V to 1.5V @ 2MHz • 28-Lead 3mm x 6mm QFN and FMEA Compliant TSSOP-28E Packages Info & Free Samples www.linear.com/product/LT8616 www.linear.com/LT86XX 100 90 1-800-4-LINEAR 80 Efficiency (%) 70 60 50 40 30 20 CH1 5VOUT CH2 3.3VOUT 10 0 0.00001 0.0001 0.001 0.01 Load Current (A) 0.1 1 , LT, LTC, LTM, Linear Technology, the Linear logo and Burst Mode are registered trademarks of Linear Technology Corporation.
