DESCRIPTION
SO-8 8 Pin Dip Contained on the chip are a series Power Supply regulator, Oscillator, control Circuitry and four Power MOS Switches. The oscillator, when unloaded, oscillates at a nominal frequency of 10 kHz, with an Input voltage of 5.0V. This frequency can be lowered by the addition of an external capacitor to the “Osc” terminal or overdriven by an external frequency source. An Oscillator “boost” function is available to increase the oscillator frequency which will optimize performance of certain parameters. The Lv input can be connected to ground to improve low voltage operation (VIN ≤ 3V), or left open for input voltages greater than 3V to reduce power dissipation. The GS7660 provides superior performance over earlier designs by combining low output impedance and low quiescent current with high efficiency and by eliminating diode voltage drop losses. The only external components required are two low cost electrolytic capacitors. FEATURES
