General Description
The AME5170 is a fixed off-time step-up DC/DC converter in a small SOT-25 package. The AME5170 is ideal for LCD panels requiring low current and high efficiency as well as LED application for cellular phone backlighting, PDAs, and other hand-held devices. The low 400ns off time allows the use of tiny external components. AME5170 is designed to drive up to four white LEDs in series with a constant current from a single Li-lon battery. To control LED brightness, the LED current can be adjusted by applying a PWM (pulse width modulated) signal with a frequency range of 100Hz to 50KHz to the EN pin.

AME8844 - 750mA CMOS LDO

General Description
The AS3336 consist of four independently controlled single-pole double-throw analog switches along with several logic gates.
This precision multiple analog switch is designed to control, multiplex & de-multiplex analog signals with a high degree of accuracy.
An improved charge injection compensation design minimizes switching transients.
AS3336 is designed on an HV CMOS process, resulting in higher speed and lower power consumption.
Each switch conducts equally well in both directions when on.
When off, they block voltages up to the power-supply levels.

Features
