双3兆赫, 1200毫安降压型稳压器具有两个300毫安的LDO Dual 3 MHz, 1200 mA Buck Regulators with Two 300 mA LDOs
Product Details
The ADP5034 combines two high performance buck regulators and two low dropout LDO regulators in a small, 24-lead 4 mm × 4 mm LFCSP QFN to meet demanding performance and board space requirements.
The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators operate in PWM mode when the load is around the nominal value. When the load current falls below a predefined threshold, the regulator operates in power save mode PSM, improving the light-load efficiency.
The two bucks operate out of phase to reduce the input capaci-tor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5034 LDOs extend the battery life of portable devices. The ADP5034 LDOs maintain power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.
Regulators in the ADP5034 are activated though dedicated enable pins. The default output voltages can be externally set in the adjustable version, or factory programmable in the fixed voltage version, and can be set to a wide range of preset values
