7 / 12 page MP28119 – ULTRA-SMALL 1.7MHZ, 600MA LOW-VOLTAGE SYNCHRONOUS STEP-DOWN CONVERTER MP28119 Rev.0.91 www.MonolithicPower.com 7 11/23/2011 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2011 MPS. All Rights Reserved. OPERATION The MP28119 is a constant frequency current mode PWM step-down converter. The MP28119 is optimized for low voltage, Li-Ion battery powered applications where high efficiency and small size are critical. The MP28119 uses an external resistor divider to set the output voltage from 0.6V to 6V. The device integrates both a main switch and synchronous rectifier, which provides high efficiency and eliminates an external Schottky diode. The MP28119 can achieve 100% duty cycle. The duty cycle D of a step-down converter is defined as: % 100 V V % 100 f T D IN OUT OSC ON Where TON is the main switch on time, fOSC is the oscillator frequency (1.7MHz), VOUT is the output voltage and VIN is the input voltage.
