1 / 4 page This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. For further information contact your local STMicroelectronics sales office. March 2012 Doc ID 022890 Rev 1 1/4 4 STEVAL-ISA079V1 High efficiency monolithic synchronous step-down regulator based on the L6928D Data brief − preliminary data Features ■ 2 V to 5.5 V battery input range ■ High efficiency: up to 95% ■ Extremely low quiescent current ■ 1 µA max. shutdown supply current ■ 800 mA max. output current ■ Adjustable output voltage from 0.6 V ■ Low dropout operation: up to 100% duty cycle ■ ± 1% output voltage accuracy ■ 1.4 MHz switching frequency externally synchronizable from 1 MHz to 2 MHz ■ Short-circuit protection ■ RoHS compliant Description The STEVAL-ISA079V1 demonstration board is based on the DC-DC monolithic regulator L6928D, specifically designed to provide extremely high efficiency. The L6928D supply voltage can be as low as 2 V, allowing it to be used in single Li-Ion cell supplied applications. Output voltage can be selected by an external divider down to 0.6 V. Duty cycle can saturate to 100%, allowing low dropout operation. The previous part number for this demonstration board was EVAL6928D. www.st.com |
