Product details

Description

The LPM3810 is a 1.2A synchronous step-down DC/DC converter which integrates an inductor and a control IC adopting current mode control in one tiny package.External Schottky diodes are not required.LPM3810 can supply 1.2A of load current from 2.5V to 5.5V supply voltage.The Output voltage is externally set by feedback resistor.The switching frequency is set at 1.5MHz, allowing the use of small surface mount capacitors.It can run 100% duty cycle for low dropout application.The LPM3810 come
