5-channel Switching Regulator Controller  
BD9730KV  
Description  
Dimension (Unit : mm)  
The BD9730KV is a 5-channel switching regulator  
controller IC designed for digital still cameras.  
This IC can be operated at 2.5V. (Min.).  
The 5-channel (4 channel for step-down and 1 channel  
for step-up)switching regulator controllers are  
integrated into a VQFP48 package. This IC can  
operate both external Bipolar and FET transistors.  
A triangle wave oscillator, a reference voltage, PWM  
comparator, a CMOS type driver, and a short protection  
circuit are all integrated in this single IC.

Features  
VQFP48  
1) Operates at a supply voltage of 2.5V (Min.)  
2) High-precision reference voltage of 1.0V±1.2%  
3) Can operate both external transistors of FET and Bipolar  
(Base current can be set by resistance.)  
4) All channels have dead time control  
5) Built-in output shutdown circuit (timer latch) when overloaded  
6) Channels 1 and 5 can externally set the reference voltage  
7) Channels 1, 4 and 5 can control independently the ON/OFF  
Applications  
Digital still camera, portable DVD player, digital movie camera, PDA, W-CDMA
