20-Lead TSSOP Package with Exposed Leadframe
The LT ? 3510 is a dual current mode PWM step-down
DC/DC converter with two internal 2.5A switches. Inde-
pendent input voltage, feedback, soft-start and power
good pins for each channel simplify complex power
supply tracking/sequencing requirements.
Both converters are synchronized to either a common
external clock input or a resistor programmable ?xed
250kHz to 1.5MHz internal oscillator. At all frequencies, a
180° phase relationship between channels is maintained,
reducing voltage ripple and component size. Programmable
frequency allows for optimization between ef?ciency and
external component size.
Minimum input-to-output voltage ratios are improved
by allowing the switch to stay on through multiple clock
APPLICATIONS
cycles, only switching off when the boost capacitor needs
recharging, resulting in ~95% maximum duty cycle.

Each output can be independently disabled using its own
soft-start pin, or by using the SHDN pin the entire part can
be placed in a low quiescent current shutdown mode.
The LT3510 is available in a 20-lead TSSOP package with
exposed leadframe for low thermal resistance.
