supply. A programmable charge pump boost converter allows the T C P 2 U PAM8904Q VOUT to operate in 1x, 2x and 3x mode. N V IN C V O The boost converter operates at a fixed frequency of 1.0MHz and CPM 1 NC provides a 9V output with a minimum number of external 1 components. PAMs unique drive technology ensures minimal inrush CPM2 CP1 current, low EMI and high efficiency. GND DIN CN2 To ensure maximum efficiency and battery life, the PAM8904Q includes an auto standby feature which puts the device in sleep mode NC VO1 while there is no valid input signal. A forced shutdown is also available to enable the IC only when required. 1 2 D N O C N C V N G To help protect the IC and system, the PAM8904Q includes overtemperature shutdown, overcurrent and short circuit protection.
