The TC7662AEPA from Micrel Inc. is a versatile charge pump voltage converter designed for efficient DC-to-DC conversion. It operates across a wide input voltage range of 3V to 18V, making it suitable for various power supply applications. This device can source increased output currents of up to 40mA, surpassing older industry standards.
Utilizing only two low-cost capacitors, the TC7662AEPA eliminates the need for inductors, reducing component count, size, and electromagnetic interference (EMI). Its on-board oscillator typically operates at 12kHz, but can be adjusted for lower supply current applications by adding an external capacitor.
The TC7662AEPA is pin-compatible with other industry-standard devices like the ICL7662 and TC7660, facilitating easy upgrades. It is available in 8-pin PDIP and 8-pin CERDIP packages, suitable for through-hole mounting. Applications include laptop computers, disk drives, process instrumentation, and micro-processor-based controllers.
The input voltage range is 3V to 18V.
The output voltage range is -3V to -18V (negative output relative to ground).
The maximum output current is 40mA.
The operating temperature range is -55°C to +125°C.
The switching frequency is 12kHz nominal.
The output impedance is 40 Ohms typical at 20mA load.
The TC7662AEPA is available in an 8-lead CDIP (Ceramic Dual In-line Package) for through-hole mounting.
