New power manager IC’s
May 09, Linear Technology Corporation designs is a leading manufacturers and marketers of standard high performance integrated circuits. The company announces the new Power manager IC’s the LTC4160 and LTC41601. They are the latest members in a family of power manager ICs for single-cell Li-Ion/Polymer battery-based applications, including media players, personal navigation devices, digital cameras, PDAs and smart phones. They each include a bidirectional switching PowerPath™ controller with automatic load prioritization, a battery charger, and an ideal diode.
The LTC4160/-1 features a bidirectional switching power manager which can power an application and charge the battery from USB. Operating in reverse, the same switching regulator can take power from the battery to generate 5V and deliver up to 500mA for USB On-The- Go (OTG) applications without any additional components.
Highly integrated boost regulator
May 7, 2009, Maxim Integrated Products,a publicly traded company that designs, manufactures, and sells high-performance semiconductor products introduced introduces the MAX17075 boost regulator with integrated charge pumps, switch control, and a high-current operational amplifier.
The device is designed based on Maxim’s proprietary high-voltage process technology and it integrates all functions required to power the source drivers, gate drivers, and VCOM backplane in LCDs. It also includes a switch for gate-driver-supply modulation. The MAX17075 is a highly integrated, step-up DC-DC converter which is a high-performance solution for LCD monitors and TVs.
