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
