It features an ultralow 2.5 \u00b5A quiescent current in Burst Mode operation while regulating 12 V input to 5 V output, making it ideal for always-on battery-powered systems. The integrated top and bottom power switches provide synchronous rectification, achieving up to 95% efficiency at 1 A load from 12 V input. The fast 30 ns minimum switch-on time enables high step-down ratios even at high switching frequencies. The device supports adjustable switching frequency from 200 kHz to 2.2 MHz and can be synchronized to an external clock. Internal compensation with peak current mode control ensures stable operation with small inductors, while the accurate 1 V EN\/UV threshold enables programmable undervoltage lockout.","working_principle":"The LT8610AHMSE-5 operates as a constant-frequency, peak current mode step-down (buck) converter. An internal oscillator sets the switching frequency between 200 kHz and 2.2 MHz based on the RT pin resistor. At each clock cycle, the integrated top NMOS switch turns on, ramping inductor current until the peak current comparator trips. The top switch then turns off and the synchronous bottom NMOS switch turns on, allowing inductor current to freewheel. The error amplifier compares a fraction of the output voltage (via the VFB pin) against a precision internal reference to set the peak current threshold. At light loads, Burst Mode operation is activated by tying SYNC low: switching pulses are delivered in bursts separated by sleep periods where all control circuitry is shut down, reducing IQ to just 2.5 \u00b5A. During overload, frequency foldback reduces the switching frequency to limit inductor current. The PG flag indicates when the output is within +\/-9% of the target voltage.","pin_description":"
