The LT3510 is a dual current mode PWM step-down DC/DC converter with two internal 2.5A switches. Independent 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 fixed 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 efficiency and external component size.

Minimum input-to-output voltage ratios are improved by allowing the switch to stay on through multiple clock 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.

Product Detail

Demo circuit 1157 is a dual monolithic step-down DC/DC converter featuring the LT3510. The demo circuit is designed for 3.3V and 1.8V outputs from a 4.5V to 24V input. The current capability of each channel is up to 2A. Both regulators features independent input voltage, feedback, soft-start and power good pins and the outputs can be configured to track each other.
