HIGH CURRENT CHARGE PUMP DC-TO-DC CONVERTER

FEATURES

GENERAL DESCRIPTION

■ Pin Compatible With TC7662/ICL7662/SI7661

■ High Output Current ....................................... 80mA

■ No External Diodes Required

■ Wide Operating Range ............................. 3V to 18V

■ Low Output Impedance ............................. 28Ω Typ.

■ No Low Voltage Terminal Required

■ Application Zener On Chip

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 8mA 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 28Ω

(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.
