LR8406 1.2MHz Synchronous Boost Converter

PIN TYPE(1) NO. NAME DESCRIPTION 1 SW Switch Pin. Connect an inductor between this pin and VIN. Keep the PCB trace lengths as short and wide as is practical to reduce EMI and voltage overshoot. If I/O the inductor current falls to zero, or pin CE is low, an internal anti-ringing switch is con.

1.2A, 1.2MHz Synchronous Boost Converter with Output Disconnect LESHAN RADIO COMPANY, LTD. /5 Series INTRODUCTION: The /5 devices provide a power supply solution for products powered by either a one-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency, which contain an internal NMOS swi.
