描述

 

The PL9001 is a 1.0A output, low-noise,pulse-width-modulated (PWM) buck-boost DC-DC converter that operates from input voltageabove, below, or equal to the output voltage.The device features two internal synchronousrectifiers for high efficiency; it requires no ex-ternal Schottky diode. Internally fixed-frequency 2.5MHz operation provides easypost-filtering and allows the use of small induc-tors and capacitors. At low load currents theconverter enters the Power Saving Mode tomaintain a high efficiency over a wide loadrange. The Power Saving Mode could be dis-abled, forcing PL9001 to operate atPWM mode. The PL9001 is ideally suited forsingle Li-Ion battery applications. It is alsouseful for three-cell alkaline, NiMH, or NiCdapplications. Shutdown mode places thedevice in standby, reducing quiescent supplycurrent to under 1μA.Other features of the PL9001 include internalsoft-start, internal compensation, short circuitprotection, current limit, and over temperatureprotection. The device is packaged in a 10-pinDFN package measuring 3 mm x 3 mm.
