TC7662 BTC7662B-8 9/11/96 EVALUATIONKITAVAILABLE 2001 Microchip Technology Inc. DS21469 ACHARGE PUMP DC-TO-DC VOLTAGE CONVERTERFEATURES Wide Operating VOLTAGE Range: to 15V Boost Pin (Pin 1) for Higher Switching Frequency High Power Efficiency is 96% Easy to Use Requires Only 2 External Non-CriticalPassive Components Improved Direct Replacement for Industry Stan-dard ICL7660 and Other Second Source DevicesAPPLICATIONS Simple Conversion of +5V to 5V Supplies VOLTAGE Multiplication VOUT = nVIN Negative Supplies for Data Acquisition Systemsand Instrumentation RS232 Power Supplies Supply Splitter, VOUT = VS/2 GENERAL DESCRIPTIONThe TC7662B is a pin-compatible upgrade to the Indus-try standard TC7660 CHARGE pump VOLTAGE converter . Itconverts a + to +15V input to a corresponding to 15V output using only two low-cost capacitors, eliminatinginductors and their associated cost, size and on-board oscillator operates at a nominal fre-quency of 10kHz.
