TC962EPA by Microchip Technology

High Output DC/DC Converter
Features
Pin Compatible With TC7662/ICL7662/SI7661
High Output Current ........................ 80mA
No External Diodes Required.
Wide Operating Range .................. 3V to 18V
Low Output Impedance ................... 28Ohm Typ.
No Low Voltage Terminal Required
Application Zener On Chip
OSC Frequency Doubling Pin Option for Smaller Output Capacitors
Description
The TC962 is an advanced version of the industry-standard 7662 high-voltage DC-to-DC converter. Using improved design techniques and CMOS construction, the TC962 can source as much as 80mA versus the 7662 ’s 20mA capability. As an inverter,the TC962 can put out voltages as high as 18V and as low as 3V without the need for external diodes. The output impedance of the device is a low 28 ? (with the proper capacitors), voltage conversion efficiency is 99.9%, and power conversion efficiency is 97%. The low voltage terminal (pin 6)required in some 7662 applications has been eliminated. Grounding this terminal will double the oscillator frequency from 12kHz to 24kHz. This will allow the use of smaller capacitors for the same output current and ripple, in most applications. Only two external capacitors are required for inverter applications. In the event an external clock is needed to drive the TC962 (such as paralleling),driving this pin directly will cause the internal oscillator to sync to the external clock.

Description
The TC962 is an advanced version of the industry standard TC7662 high voltage DC-to-DC converter. Using improved design techniques and CMOS construction, the TC962 can source as much as 80 mA versus the 7662’s 20 mA capability. As an inverter, the TC962 can put out voltages as high as 18V and as low as 3V without the need for external diodes. The output impedance of the device is a low 28 (with the proper capacitors), voltage conversion efficiency is 99.9%, and power conversion efficiency is 97%. The low voltage terminal (pin 6) required in some TC7662 applications has been eliminated. Grounding this terminal will double the oscillator frequency from 12 kHz to 24 kHz. This will allow the use of smaller capacitors for the same output current and ripple, in most applications. Only two external capacitors are required for inverter applications. In the event an external clock is needed to drive the TC962 (such as paralleling), driving this pin directly will cause the internal oscillator to sync to the external clock. Pin 1, which is used as a test pin on the 7662, is a voltage reference Zener on the TC962. This Zener (6.4V at 5 mA) has a dynamic impedance of 12 and is intended for use where the TC962 is supplying current to external regulator circuitry and a reference is needed for the regulator circuit. (See Section 3.0 “Applications Information” Applications Information). The TC962 is compatible with the LTC1044, SI7661 and ICL7662. It should be used in designs that require greater power and/or less input to output voltage drop. It offers superior performance over the ICL7660S.
