TC7660SEOA713 Charge Pump by Microchip Technology An Introduction

The TC7660SEOA713, manufactured by Microchip Technology, stands out as a versatile charge pump DC-to-DC converter specifically designed for inverting or doubling voltage rails in low power applications. Housed in a compact 8-pin SOIC package with 3.90 mm width, the device simplifies negative voltage generation by providing inductorless switching regulation at a fixed 20mA output current. For design engineers seeking efficiency and board space savings, the TC7660SEOA713 responds to contemporary requirements in analog circuit design, offering a plug-and-play solution for both positive and negative voltage rails.

Main Functions and Notable Attributes of TC7660SEOA713

At its core, the TC7660SEOA713 operates as a charge pump switching regulator. Unlike traditional DC/DC converters that require inductors and complex control loops, this device leverages switched-capacitor topology to invert input voltages or double them to create necessary supply rails. Its single-output configuration—delivering up to 20mA—caters to various analog tasks including op amp biasing, sensor conditioning and reference voltage generation. As part of Microchip’s analog and interface product suite, it provides an efficient pathway to generate negative or higher voltage levels with minimal external components, reducing bill-of-materials and development risk.

The charge pump method exploits capacitor switching to transfer energy, which is ideal for load profiles up to tens of milliamperes where ripple and transients must be carefully managed but power demands remain modest. The TC7660SEOA713 ensures high conversion efficiency and stability within these operational envelopes, making it well-suited for portable battery-powered devices and energy-sensitive industrial systems.

TC7660SEOA713’s Packaging Options and Electrical Specifications

One of the defining attributes of the TC7660SEOA713 is its small-form-factor 8-SOIC package, enabling integration within densely populated PCB layouts. The device supports a wide ambient operating temperature range, which is critical for automotive, industrial and consumer environments. Electrical specifications are engineered for reliability—regulated output currents, stable operation near maximum recommended temperature of 85°C, and minimized output noise. The absence of inductors further reduces height profiles, promoting designs with ultra-thin mechanical constraints.

Use Cases of TC7660SEOA713 in Contemporary Electronic Devices

The TC7660SEOA713 is particularly relevant in designs where creating a negative supply is either mandatory for amplifier rails, analog sensor circuits, or analog reference voltages. For example, precision instrumentation amplifiers often require symmetric ±V supplies that traditional power topologies may not furnish efficiently. The TC7660SEOA713 offers engineers the flexibility to invert +5V to obtain –5V for analog stages without recourse to bulky or costly magnetics. Similarly, doubling functions can aid in powering specialized analog blocks when available input rails are insufficient.

Its modest output current and efficient charge-pump design make it a preferred choice for portable electronics—such as handheld measurement devices, sensor nodes, and battery-powered consumer products—where PCB space, power consumption, and form factor are primary considerations.

Benefits of Incorporating TC7660SEOA713 in Microchip’s Analog Product Line

Selecting the TC7660SEOA713 offers further advantages when integrating with the expansive Microchip analog and interface portfolio. It harmonizes with other solutions—such as thermal management ICs, voltage references, op amps, linear and switching regulators—enabling complete system designs under a unified platform. This promotes easier design support, streamlined sourcing and technical compatibility. Microchip’s quality assurance, certified by ISO/TS-16949:2002, guarantees reliability across automotive, industrial and communication market segments. Designers benefit from direct access to technical resources, evaluation tools, and training for rapid prototyping and troubleshooting.

Possible Substitutes or Alternative Models for TC7660SEOA713

When considering alternatives or future-proofing designs, engineers may evaluate similar charge pump inverters or voltage doublers from Microchip’s product family and other reputable suppliers. Devices in the TC7660 series—such as TC7660S—may offer slight variations in output current, voltage conversion ratios or packaging options. Additionally, evaluating pin-for-pin compatibility, output regulation performance, maximum current ratings or package dimensions is essential when substituting or scaling solutions. Staying within the Microchip ecosystem ensures seamless technical support and sustained product longevity.
