MAX860ESA+T

MAX860ESA+T Description

The MAX860ESA+T is a high-performance, ratiometric charge pump DC-DC switching voltage regulator from Analog Devices Inc./Maxim Integrated. Designed for flexibility, it supports both positive and negative output configurations with a fixed output type. The device operates over a wide input voltage range (1.5V to 5.5V), making it suitable for diverse power supply scenarios. With a 50mA output current capability and selectable switching frequencies (6kHz, 50kHz, or 130kHz), it balances efficiency and noise performance. Housed in an 8-pin SOIC package, it is optimized for surface-mount applications and is available in Tape & Reel (TR) packaging for automated assembly.

MAX860ESA+T Features

• Ratiometric Function: Ensures precise voltage scaling relative to input, ideal for sensor and measurement systems.
• Wide Input Range (1.5V–5.5V): Supports low-voltage battery-powered and portable applications.
• Configurable Output: Generates positive or negative voltages from a single input, reducing component count.
• Selectable Frequencies (6kHz/50kHz/130kHz): Allows trade-offs between efficiency (lower freq) and reduced ripple (higher freq).
• Low External Component Count: Charge pump topology eliminates inductors, simplifying PCB design.
• Robust Compliance: ROHS3 and REACH compliant, with MSL 1 (Unlimited) moisture sensitivity for reliable storage.
