ISL85402 - 2.5A Regulator

ISL85402 Description

ISL85402 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL85403 2.5A Regulator with Integrated High-Side MOSFET for Synchronous Buck .
PIN NAME EN FS SS FB COMP ILIMIT MODE PGOOD PHASE EXT_BOOST PIN # DESCRIPTION 1 The controller is enabled when this pin is left floating or pulle.

ISL85402 Features

* Buck Mode: Input Voltage Range 3V to 36V (Refer to “Input Voltage” on page 13 for more details)
* Boost Mode Expands Operating Input Voltage Lower Than 2.5V (Refer to “Input Voltage” on page 13 for more details)
* Selectable Forced PWM Mode or PFM Mode
* 300µA IC Qu

ISL85402 Applications

* The low-side driver can be either used to drive an external low-side MOSFET for a synchronous buck, or left unused for a standard non-synchronous buck. The low-side driver can also be used to drive a boost converter as a pre-regulator followed by a buck controlled by the same IC, which greatly expa
