AIC2385——1.5A Synchronous PWM/PSM Step-Down DC/DC Converter

Description
AIC2385 is a low noise, pulse width modulation (PWM) DC-DC buck converter. The device has an adjustable version.
The device uses an internal synchronous rectifier with high efficiency; no external Schottky diode is required. AIC2385 is very suitable for lithium ion battery applications. PWM / PSM mode extends battery life by switching to pulse skip modulation mode during light loads. Shutdown mode keeps the device in standby and reduces the power supply current to less than 1uA.
Other characteristics of AIC2385 include high efficiency, low voltage loss, short circuit protection, over temperature protection and over voltage protection. Packaging SOT23-5.

Application
1. LCD TV
2. Multi-function peripherals
3. Mobile phone
4. CPU I / O power supply
5. Battery drive

AIC6163——1A Single Channel USB Switch

Description
The AIC6163 integrates an 85-megaohm high-side power switch for self-powered and bus-powered universal serial bus (USB) applications. The input voltage range of this switch is 3.2V to 6.5V, which is ideal for 5V systems.
The protection includes current limiting and foldback, short circuit and thermal shutdown. AIC6163 is ideal for any system that requires current limiting and power control. The AIC6163 has a low quiescent current and a small package, making it ideal for battery-powered portable applications.
The guaranteed minimum output rise time limits the inrush current during hot swapping and minimizes EMI, preventing excessive voltage drop at the upstream port.

Application
1. USB power management
2. High-voltage side power protection switch
3. Hot-plug power supply
4. Battery charger circuit
5. Portable application
6. Digital TV
