FFF CompatibilityThe pinout matches the target part exactly, including Pin 7 shutdown logic and Pin 1 frequency control.Both parts use the exact same 8-SOIC package footprint.Operates at higher switching frequencies (500kHz/1MHz vs. 125kHz/250kHz), which may require smaller charge-pump capacitors.Pin 7 is OSC (Oscillator Input) rather than SHDN (Shutdown). If shutdown capability is utilized in the design, a layout change is required.Both parts use an industry standard SOIC-8 package.Meets or exceeds all major electrical parameters, including a higher output current capability.
AI Summary

MAX1680ESA+T by Analog Devices: Charge Pump Switching Regulator IC Positive or Negative Fixed -Vin, 2Vin 1 Output 125mA 8-SOIC (0.154", 3.90mm Width).

This sibling variant from the same series is a drop-in physical replacement, though it operates at higher switching frequencies which may require re-optimizing the values of the external capacitors.

  • Same device family pinout including shutdown logic on Pin 7
  • Identical SOIC-8 package and footprint dimensions
  • Maintains high 125mA output current rating
  • Higher switching frequency (500kHz/1MHz vs 125kHz/250kHz)
  • Requires smaller external capacitors (typical 1uF vs 4.7uF) for optimal ripple and efficiency

A high-performance alternative from Texas Instruments that provides a higher output current rating of 200mA, but lacks the logic-controlled shutdown function on Pin 7 (replaced by oscillator control).

  • Higher maximum output current (200mA vs. 125mA)
  • Very low output resistance (3.5 Ohms typical)
  • Wide input supply voltage range (1.5V to 5.5V)
  • No logic-controlled shutdown on Pin 7 (Pin 7 is OSC)
  • Lower switching frequency (10kHz/75kHz)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
