产品概述

描述

The STEVAL-ISA152V1 product evaluation board is a step-down switching power supply based on the L7987 regulator in an HTSSOP16 package. The output voltage can be set starting from 0.8 V. Low drop-out operation, with almost 100% duty cycle, can be achieved. The L7987 is a 61 V, 3 A step-down asynchronous switching regulator with embedded power MOSFET caable of delivering up to 3 A of current, depending on the application conditions.
The embedded switch-over feature on the VBIAS pin and the light load management (pulse skipping) are intended to maximize power conversion efficiency across the entire load range.
The soft-start, current limit threshold and the switching frequency are adjustable for application optimization.
The device includes an internal 250 kHz oscillator that can be externally adjusted up to 1.5 MHz; two L7987 regulators can be synchronized in a 180° out-of-phase configuration for reduced total input RMS current
