Product details

Active production — straightforward BOM line

The MAX1952ESA+: That means it is a clean line-item for both new designs and maintenance replenishment — no last-time-buy planning or substitute qualification needed.

2 A output, fixed 1.8 V rail

The fixed output means no external resistor divider is needed; the BOM simply matches the rail voltage. The internal synchronous rectifier replaces the usual freewheeling diode with a low-Rds(on) FET, improving efficiency at higher output currents — particularly relevant when the load regularly draws close to the 2 A ceiling. Switching frequency spans 800 kHz to 1.1 MHz, allowing the designer to trade off inductor size (higher frequency, smaller inductor) against switching losses and EMI. The frequency is set by an external resistor; the range covers the common sweet spot for compact power supplies.

Industrial temperature, standard SOIC-8 footprint

It does not extend to the +125°C automotive grade, so under-hood or engine-bay deployment would require a different part. Housed in an 8-pin SOIC (0.154" wide, 3.90 mm body width), the MAX1952ESA+ uses a standard surface-mount footprint that is easy to route, inspect, and rework.

Compliance and sourcing posture

ROHS3 compliant — no exemptions or substance declarations to manage for EU or similar regulated markets.

Frequently asked questions

Is MAX1952ESA+ RoHS compliant?

Yes, it is ROHS3 compliant, meaning it contains no restricted substances above the threshold limits and requires no exemption paperwork.
