Power Management IC
Maxim introduces the MAX8620Y, a micro-power management integrated circuit (microPMIC). This device integrates a 500 mA step-down DC/DC converter, two 300 mA low-dropout linear regulators, and a 30 ms reset into a 9 mm2 TDFN package with a maximum height of 0.8 mm. Applications for the device include cell phones, smartphones, and MP3 players. Providing up to 92% efficiency, the 4 MHz synchronous step-down D/DC converter uses a 1 microhenry inductor and small ceramic capacitors. Its 100 ns transient response fits processor applications like graphics processing, video streaming, and gaming. The two LDOs provide low noise 45 microvolts root-mean-square output, and their output voltages are pin-programmable to save size and maintain flexibility. The reset output warns the system of impending power loss, thereby allowing safe shutdown.
