Overview
Description
The ISL85033 is a wide input range, dual-standard buck converter that can be configured to provide a negative output voltage. The ISL85033-12VEVAL3Z evaluation board is used to demonstrate the negative configuration. In this configuration, VIN can range from 4.5V to (28V - VOUT).
The ISL85033 is offered in a 4mm x 4mm 28-ld TQFN package with a 1mm maximum height. The complete converter occupies 6.25cm2 area.
Features
- Wide input voltage range from 4.5V to (28V - VOUT)
- Adjustable and synchronizable negative output voltage with continuous output current up to 5A, depending on VOUT and VIN
- Current mode control
- Adjustable switching frequency from 300kHz to 2MHz
- Power-good detection (referenced to VOUT)
- Externally adjustable soft-start time
- Overcurrent and hiccup mode short circuit protection, thermal overload protection, and undervoltage lockout (UVLO)
- Boot undervoltage detection
- Default out-of-phase channels reduce voltage ripple and component size; user-selectable phase operation
