STEVAL-ISA198V1 Buck Converter Evaluation Board for L7987L


The STEVAL-ISA198V1 evaluation board is a step-down switching power supply based on the L7987L regulator device. The L7987L is an asynchronous buck switching regulator with an embedded power MOSFET.

• Input Voltage Range: +4.5V to +60Vdc

• Step-down (buck) conversion

• Output voltage: +5Vdc (Vin > +6V)

• Output current: up to 2A

• Switching frequency: 500kHz

• 5ms programmed soft-start

• Compatible with ceramic output capacitors

• Light-load management (pulse skipping)

• Switch-over feature on the Vbias pin

• Adjustable soft-start, current limit threshold and switching frequency

• 180° out of phase synchronization available with another L7987L device

• Auto-recovery overcurrent and thermal protection
