General Description

The GS1663 ZT is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.15Ω

power MOSFET makes this converter highly power efficiently. Selectable high switching frequency

allows faster loop response and easy filtering with a low noise output. The non-inverting input its error

amplifier is connected to an internal 1.24V precision reference voltage. Soft-Start time can be

programmed with an external capacitor, which sets the input current ramp rate. Current mode control

and external compensation network make it easy and flexible to stabilize the system.

Features

 Adjustable Output from V_CCto 12V

 Internal Fixed PWM Frequency: 640KHz / 1.2MHz

 Frequency Selection Pin

 Precision Feedback Reference Voltage: 1.24V

 Internal 0.15Ω, 3A, 14V Power MOSFET

 External Programmable Soft-Start Function (SS)

 Shutdown Current : 0.1µA

 Over Current Protection

 Package: SOP-8L (EP)

Applications

 LCD Displays

 Digital Cameras

 Handheld Devices

 Portable Products
