DESCRIPTION

The LT?8650SP is a dual step-down regulator that delivers

up to 6A of continuous current from both channels with a

heat sink and supports loads up to 8A from each channel.

The LT8650SP features second generation Silent Switcher

architecture to minimize EMI emissions while delivering

high efficiency at high switching frequencies. This includes

integration of bypass capacitors to optimize high frequency

current loops and make it easy to achieve advertised EMI

performance by eliminating layout sensitivity. The top of the

package features exposed die for heat sink attach which is

required to meet maximum output current ratings.

The fast, clean, low-overshoot switching edges enable high

efficiency operation even at high switching frequencies,

leading to a small overall solution size. Peak current mode

control with a 40ns minimum on-time allows high step

down ratios at high switching frequencies.

Burst Mode operation features a 6.2μA quiescent current

resulting in high efficiency at low output currents, forced

continuous mode allows fixed switching frequency operation

over the entire output load range, and spread spectrum

operation can further reduce EMI emissions. External VC

pins allow optimal loop compensation for fast transient

response. The VC pins can also be used for current sharing

and the CLKOUT pin enables synchronizing two LT8650SP

chips to generate a 4-phase, 24A supply.
