XC9276 Series ETR05070-001 Ultra-Low Quiescent Current, Synchronous Step-Down PFM DC/DC Converter
with Output voltage selectable function
☆Green Operation compatible ■GENERAL DESCRIPTION
The XC9276 Series is a 150mA step-down synchronous rectification DC/DC converter which has an output voltage switchover function with an ultra-low power consumption circuit and a PFM control.
The efficiency performance at a light load current is dramatically improved by implementing ultra-low power consumption
circuits which has 200nA consumption current, and PFM control method. Additionally two-preset output voltage switchover
function is available with using VSEL pin.
This function can select an appropriate output voltage based on the MCU behavior mode and contribute a power
consumption reduction for a total system. Due to these functions, XC9276 series are suitable for equipment which needs a
high efficiency performance at a light load current, and a long-time battery life.
XC9276 series are compatible to 2.2uH inductor therefore it can reduce an output ripple voltage which is a negative side of
PFM control method, and a PCB board area size. ■FEATURES ■APPLICATIONS

Descripción detallada

La serie XC9276 son convertidores de CC / CC reductores de corriente síncrona de baja intensidad de reposo ultrafino tipo PFM con un controlador Pch incorporado de 0.3Ω (TYP.) Y un transistor de conmutación síncrona de 0.3Ω (TYP.) Nch con función seleccionable de voltaje de salida, diseñado para Permitir el uso de condensadores de cerámica.

El control PFM permite una corriente de reposo ultrabaja, lo que hace que estos productos sean ideales para dispositivos que funcionan con baterías que requieren alta eficiencia y una larga vida útil de la batería.

Solo se necesitan capacitores inductores, CIN y CL como piezas externas para reducir el circuito de CC / CC. El rango de voltaje es de 1.8V a 6.0V. Este producto tiene dos voltajes de salida fijos de 0.6V a 3.6V (precisión: ± 2.0%) en incrementos de 0.1V. Mediante el terminal SET, el voltaje de salida es seleccionable entre dos voltajes preestablecidos para suministrar un voltaje ideal basado en el estado de la aplicación. Durante el modo de espera, todos los circuitos se apagan para reducir el consumo a 0.1 μA o menos.
