MAP7154

MAP7154 – 6MHz, 800mA Buck Converter for RFPA Confidential Datasheet Version 1.0 Datasheet – MAP7154 6MHz, 800mABuck Converter for RFPA General Description The MAP7154 is synchronous buck converter for 3G, 3.5G and 4G RFPA (RF Power Amplifier). The MAP7154 can operate at 6MHz switching frequency and has 2.7V to 5.5V input voltage range, 800mA output current capability. The MAP7154 has three output modes. In Seep mode, output regulation is not required and MAP7154 may be entering in Sleep mode by setting VREF nominally to 100mV, also very low IQ operation. In Buck mode, output voltage can be programmed from 0.4V to 3.50V in proportion to VREF input voltage ranged from 0.16V to 1.40V. Output voltage is the same with input voltage in bypass mode. Bypass mode reduces the voltage drop to less than 60mV. These features enable RFPA to operate at higher power efficiency saving its output power. The MAP7154 has the protections, input under voltage lockout, thermal shutdown and over curr...
