April 2012 Doc ID 023076 Rev 1 1/4 4 STEVAL-ISA097V1 2 A step-down switching demonstration board based on the L7985 in DFN10 package Data brief Features ■ 2 A DC output current ■ From 4.5 V to 38 V range input voltage ■ Output voltage adjustable from 0.6 V ■ 250 kHz switching frequency programmable up to 1 MHz ■ Internal soft-start and enable ■ Low dropout operation: 100% duty cycle ■ Voltage feed-forward ■ Zero load current operation ■ Overcurrent and thermal protection ■ RoHS compliant Description The STEVAL-ISA097V1 demonstration board is a step-down switching power supply based on the L7985 in DFN10 package. The L7985 is a step-down regulator with a 2.5 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz. www.st.com |
