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

Detailed Description

XC9276 series are Ultra Low Quiescent Current synchronous-rectification type PFM step down DC/DC converters with a built-in 0.3Ω (TYP.)Pch driver and 0.3Ω (TYP.) Nch synchronous switching transistor with Output voltage selectable function, designed to allow the use of ceramic capacitor.

PFM control enables an ultra-low quiescent current, making these products ideal for battery operated devices that require high efficiency and long battery life.Only inductor, CIN and CL capacitors are needed as external parts to make a step down DC/DC circuit.Operation voltage range is from 1.8V to 6.0V.

This product has fixed two output voltage from 0.6V to 3.6V(accuracy: ±2.0%) inincrements of0.1V.By SET terminal the output voltage is selectable among two preset voltages to supply an ideal voltage based on the status of the application. During stand-by, all circuits are shutdown to reduce consumption to as low as 0.1μA or less.
