Manufacturer Part Number

MAX665CPA

Description

This is an integrated circuit (IC) charge pump switching regulator designed for power management applications. It can create a regulated output of either the negative input voltage (inverter mode) or twice the input voltage (doubler mode), using minimal external components. The device is housed in an 8-pin DIP package, making it easy to mount on through-hole PCBs. It is intended for low-power applications, capable of supplying up to 100mA output current. The MAX665CPA is now obsolete but may still be used in designs requiring simple and low-cost voltage conversion.

Device Structure

The chip integrates a charge pump switching regulator circuit, with internal switching transistors. It is capable of switching between inverter and doubler configurations using a ratiometric principle. The 8-DIP package allows straightforward PCB integration for prototyping or legacy equipment.

Performance Characteristics

Provides up to 100mA output current

Simple design, requires only a few external capacitors

Operates at two switching frequencies (10kHz/45kHz) for flexibility in noise or efficiency needs

No synchronous rectifier, better suited for low to moderate current, low efficiency critical applications

Reliable operation within specified input and temperature ranges

Application Environments

Suitable for applications needing negative or doubled voltages from a single supply

Used in analog and digital circuit biasing, LCD bias, portable instrumentation, back-lighting, or where op-amp rails are required

Use in designs where through-hole assembly is necessary or serviceability is important

Used for legacy/maintenance work due to its obsolete status

Selection Guidelines

Input voltage must be between 1.5V and 8V

Output requirements must not exceed 100mA

Select if simple voltage inversion or doubling is needed and design constraints allow for DIP packages

Choose only for non-RoHS compliant designs (lead in package allowed)

Consider alternative parts for new designs since it is obsolete

Usage Considerations

Observe maximum ratings for input voltage and load current to prevent damage

Use correct external capacitors for charge pump operation as recommended in the datasheet

Not suitable for high-current or stringent efficiency applications

Check for available stock since the device is obsolete

Not RoHS compliant, may not be suitable for new, lead-free designs

Limited to 0°C to +70°C, not suited for extreme temperature environments

Potential Equivalent/Replacement Models
