APW34063
1.5A, DC/DC Switching Regulators
Features
General Description
The APW34063 is a monolithic control circuit con-
taining the primary functions required for DC-to-DC
converters. This device consists of an internal tem-
perature compensated reference, comparator, con-
trolled duty cycle oscillator with an active current limit
circuit, driver and high current output switch. This
device was specifically designed to be incorporated
in Step-Down and Step-Up and Voltage-Inverting ap-
plications with a minimum number of external
components.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte in plate termina-
tion finish; which are fully compliant with RoHS and compatible with both SnPb and lead-free soldiering operations.
ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J STD-020C for MSL classifica-
tion at lead-free peak reflow temperature.
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise
customers to obtain the latest version of relevant information to verify before placing orders.

Electrical Characteristics
Note :
2.Tlow=0°CV, Thigh=+70°C
3.Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient
temperature as possible.
4.If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (£300mA) and high driver
currents (³ 30mA), it may take up to 2.0ms for it to come out of saturation. This condition will shorten the off time at frequencies³ 30kHz,
and is magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot
saturate. If a non-Darlington configuration is used, the following output drive condition is recommended :
IC output
³
Forced b of output switch :
10
IC driver - 7.0mA*
* The 100W resistor in the emitter of the driver device requires about 7.0mA before the output switch conducts.

The following power supply characteristics must be chosen :
Vin - Nominal input voltage.

fmin - Minimum desired output switching frequency at the selected values of Vin and Io.
Vripple(pp) - Desired peak-to-peak output ripple voltage. In practice, the calculated capacitor value will need
to be increased due to its equivalent series resistance and board layout. The ripple voltage should
be kept to a low value since it will directly affect the line and load regulation.
