The A-revision improves EMI performance with controlled edge rates on the switch node. The synchronous design eliminates the external Schottky diode by using an internal low-side MOSFET (catch FET) for freewheeling, improving efficiency by 3-5% compared to asynchronous designs. The device uses a current-mode control architecture: an error amplifier compares the FB voltage with the 0.97V internal reference; the error amplifier output controls the peak inductor current; the peak current is sensed cycle-by-cycle for stability and current limiting. The switching frequency is fixed at 1MHz (also available in 2MHz for LT8610AB-2), allowing small 2.2-4.7uH inductors. The burst mode operation is the key low-Iq feature: at light load (below approximately 100mA), the device delivers a burst of switching cycles, then enters a low-Iq sleep state where only the reference and error amplifier remain active (2.5uA total). This results in extremely low standby power consumption, critical for always-on automotive and battery-powered systems. The minimum on-time is 50ns, allowing high step-down ratios (e.g., 42V to 3.3V at 1MHz). The EN\/UV pin can set a precise undervoltage threshold using a resistor divider. The TR\/SS pin provides programmable soft-start and voltage tracking (for sequencing multiple rails). The -BEMSE#TRPBF suffix specifies MSOP-10, tape-and-reel, lead-free.","pin_description":"
