MB39C326 is a high efficiency, low noise synchronous, 6MHz buck-boost DC/DC converter
designed for powering the radio frequency power amplifiers (RFPA) in mobile handsets or
other mobile applications with single-cell Li-ion battery. MB39C326 DC/DC convertor
switches at 6MHz compare to conventional DC/DC converters that have switching
frequencies between 2 to 3MHz, allowing smaller inductor to be use and expect to reduce
the overall board space of the power management circuits by half. Its buck boost operation
switches automatically to extend the operating voltage of lithium battery while providing
stable power supply to the power amplifier.

MB3793 is a power voltage monitoring IC with dual-system watchdog
timer. A reset signal is output at transient power cut-off or power fall.
When the power resumes, the IC outputs a power-on reset signal to MPU
to monitor power voltage. Using this IC in an MCU system can provide
such system with a fail-safe function.

Power Management IC for Portable Instruments 6MHz Synchronous Rectification Buck Boost DC/DC Converter IC
MB39C326
This product is a power management IC for portable instruments that has a highly effective buck boost DC/DC converter, which expands the
available input voltage range. It can be loaded on a small 2.15mm × 1.94mm package(Photo 1), and can configure a power system with a small
footprint at low BOM cost, with its built-in switching FET. By inputting signals such as DAC, it can control the output voltage value dynamically.

■ Figure 2 Conversion Efficiency of MB39C326
This product is a highly effective and low-noise 6MHz buck boost DC/DC
converter IC that has been developed for mobile instruments using a one-cell
lithium-ion battery. With its high operating frequency (6MHz), the inductor
size can be significantly reduced compared with existing 2 to 3MHz products,
and the board area of the power part can be downsized by half (Figure 1).
Since our unique buck boost circuit switches automatically between the
voltage increasing operation and the voltage decreasing operation against
input voltage, power is supplied stably even when the inputting battery
voltage decreases, and the system driving time can be expanded through
the effective utilization of the remaining power in the battery.

High efficiency with the PFM/PWM auto-switching mode
The DC/DC circuit features the PFM/PWM auto-switching mode (power-save

can be operated in by setting the XPS terminal to the H level (Table 2).

Overcurrent protection function
This function controls the current to prevent higher output current than the
setting from flowing. Also, when the output current reaches the current limit
value, the output voltage starts dropping. The overcurrent protection function
detects current flowing from the built-in P-ch MOSFET (overcurrent protection
function) that connects the VDD terminal to the external inductor. The current
limit value can be selected from three values, according to the XPS terminal
and the ILIMSEL terminal theory, as shown in Table 2.
