Microchip Technology, Inc. Hi Voltage Dc-Dc Converter Rohs Compliant Microchip TC7662BCPA

The Hi Voltage DC-DC Converter, part number 30AC1152, is a charge pump voltage converter designed to convert input voltages ranging from 1.5V to 15V into corresponding negative output voltages from -1.5V to -15V. It achieves high power efficiency of up to 96% and operates with only two external capacitors, eliminating the need for inductors, which reduces cost, size, and electromagnetic interference (EMI). This device is a pin-compatible upgrade to the industry-standard TC7660, making it suitable for applications such as simple conversion of +5V to ¬±5V supplies, voltage multiplication, and negative supplies for data acquisition systems and instrumentation. The on-board oscillator operates at a nominal frequency of 10kHz, which can be increased to 35kHz for smaller external capacitors by connecting the boost pin to V+. The TC7662B is available in both 8-pin DIP and SOIC packages, with operating temperature ranges of 0¬8C to +70¬8C or -40¬8C to +85¬8C, depending on the specific variant. Engineers considering this product should note its ease of use, high efficiency, and compatibility with existing designs that utilize the TC7660.
