CE8406 - 1.2MHz Synchronous Boost Converter
PIN TYPE(1) NO.
NAME DESCRIPTION 1 SW 2 GND 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 i
1.2A, 1.2MHz Synchronous Boost Converter with Output Disconnect CE8406 Series 1.2A, 1.2MHz Synchronous Boost Converter with Output Disconnect CE8406 Series INTRODUCTION: The CE8406 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 m
