INTERSIL ISL6237 ISL 6237 QFN-32Brand New ISL6237 QFN 32 The ISL6237 dual step down, switch mode power supply (SMPS) controller generates logic supply voltages in battery powered systems. The ISL6237 includes two pulse width modulation (PWM) controllers, 5V 3. 3V and 1. 5V 1. 05V. The output of SMPS1 can also be adjusted from 0. 7V to 5. 5V. The SMPS2 output can be adjusted from 0. 5V to 2. 5V by setting REFIN2 voltage. This device features a linear regulator providing 3. 3V 5V, or
Brand New ISL6237 QFN-32
The ISL6237 dual step-down, switch-mode power-supply (SMPS) controller generates logic-supply voltages in battery-powered systems. The ISL6237 includes two pulse-width modulation (PWM) controllers, 5V/3.3V and 1.5V/1.05V. The output of SMPS1 can also be adjusted from 0.7V to 5.5V. The SMPS2 output can be adjusted from 0.5V to 2.5V by setting REFIN2 voltage. This device features a linear regulator providing 3.3V/5V, or adjustable from 0.7V to 4.5V output via LDOREFIN. The linear regulator provides up to 100mA output current with automatic linear-regulator bootstrapping to the BYP input. When in switchover, the LDO output can source up to 200mA. The ISL6237 includes on-board power-up sequencing, power-good (POK_) outputs, digital soft-start, and internal soft-stop output discharge that
prevents negative voltages on shutdown.
