1 / 14 page  Features Schottky Diode Embedded, Saving Cost and Space Low Start-up Voltage (0.9V) Pagers Cameras Wireless Microphones Pocket Organizers Battery Backup Suppliers Portable Instruments Pb-Free Package Applications General Description n n n n n n n n n n n n n n High Efficiency up to 88% Low Quiescent Current Low Ripple and Noise Available Output Voltage: 2.0V,2.7V,2.8V, and 5.0V Space Saving Packages: SOT-89, SOT-23 The PAM2400 is a high efficiency step-up DC/DC converter, delivering a fixed output voltage of The device starts up with an input voltage as low as 0.9V at 1mA load. The P ulse F requency Modulation (PFM) scheme provides optimized performance for applications with light load and low input voltages. The PAM2400 employs a built-in synchronous rectifier, instead of requiring an external Schottky diode, so that to improve system efficiency and save system cost and PCB area. The internal PFM control circuit operates at constant switching frequency of The space saving SOT-89 and SOT-23 packages make the PAM2400 ideal for s pace c onscious applications. 3.0V, 3.3V,3.8V 2.0V, 2.7V, 2.8V, 3.0V, 3.3V, 3.8V or 5.0V. 100KHz.
