一,产品概述(General Description)

The JTMT9106/JTMT9107 series are reference voltage (Vref) apply external step-up DC/DC controller ICs. Output voltage will be
set with external resistors (RFB1 and 2) and Vref value. The series make it easy to control output voltage externally and are
suited to software applications that need to vary voltage, such as LCD power supply for PDA. Output will be stable no matter
which load capacitors are used but if a low ESR capacitor is used, RSENSE of about 0.1 will be required and phase compensation
will be achieved. This makes the use of ceramic capacitors much easier, and allows for lower output ripple and reduced PCB
area requirements. Tantalum and electrolytic capacitors can also be used, in which case, RSENSE becomes unnecessary.
Oscillation frequencies of high clock, low ripple 300kHz and low supply current 100kHz are available. The JTMT9107 series are
PWM controlled. Control switches from PWM to PFM during light loads with the JTMT9107 and the series is highly efficient from
light loads to large output currents.
