Intersil – New “Party of Five” Highly Integrated Synchronous Buck Regulators – Feature-rich ISL8018 and Tiny ISL8003x Family of Devices
Today Intersil announced five new highly integrated synchronous buck regulators that step-down 5V rails to point-of-load (POL) inputs as low as 0.6V for FPGAs, DSPs and microprocessors.
The feature-rich ISL8018 delivers up to 8A of continuous output current from a 2.7V to 5.5V input supply, while offering up to 97% efficiency and higher integration than competitive devices. The 2 x 2mm ISL8003x family of devices delivers up to 3A of continuous output current from a 2.7V to 5.5V input supply and offers up to 95% peak efficiency for delivering general POL conversions in telecom, cloud computing, industrial, instrumentation and medical equipment.
More information about the ISL8018 and the ISL80030/A/31/A can be found on the Intersil website.

Key Features and Specifications of ISL8018
- Delivers high peak efficiency up to 97% in a compact 0.15 inch2 footprint
- +/-10% output voltage margining
- Output voltage is adjustable from 0.6V to Vin, with a fixed output voltage option
- Adjustable current limit
- External synchronization up to 4MHz, with master-to-slave phase shifting capability
- Provides 1% reference accuracy over temperature, load and line
- Adjustable switching frequency from 500kHz to 2MHz, with default at 1MHz
- Start-up with pre-bias output, internal soft-start — 1ms or adjustable, internal/external compensation
- Soft-stop output discharge during disabled
- Peak current limiting, hiccup mode short circuit protection and over-temperature protection
Key Features and Specifications of ISL80030/A/31/A
- Deliver high peak efficiency up to 95%, with 3A maximum output current
- Switching frequency up to 2MHz
- Provides quiescent current as low as 35uA
- Selectable PFM or PWM operation
- Short-circuit protection, and over-current, negative current, over-temperature/thermal protection
- Internal soft-start and soft-stop
- Vin under-voltage lockout and Vout over-voltage protection
These synchronous buck regulators can be combined with the ISL85033 dual 3A output synchronous buck regulator in POL applications, and the ISL85003 4.5V to 18V, 3A synchronous buck regulator for a two-stage solution converting a 12V rail to a 5V rail. The ISL85403 also can be used for a two-stage solution to step-down a 24V rail to a 5V rail.
Both products have demo boards which can jump-start customer designs with Intersil: ISL8018DEMO1Z, ISL80030DEMO1Z and ISL80031DEMO1Z. To fully evaluate the ISL8018 IC we also offer the ISL8018EVAL3Z.
