1 General Description
The AS1330 is a synchronous, low voltage, high efficiency DC-DC
boost converter running at a constant frequency of 4MHz. This very
high oscillator frequency allows the usage of a very a small and low
profile inductor with only 470nH. This results in a board space
requirement of only 43mm2 for the complete solutions including all
external components.
AS1330 generates an output voltage between 1.8 and 3.3V from
input voltages down to 0.6V. Therefore it is ideal for application
powered by a single cell battery. AS1330 provides an output current
of 150mA @ 3.3V from a single cell.
To support high efficiency across the entire load range
the AS1330 is equipped with a synchronous rectifier and
features a power save mode for light loads.
To avoid harmful deep discharge of the battery during shutdown the
AS1330 is equipped with an output disconnect function.
AS1330 can either monitor the battery voltage (Sense pin) or report
the status of the output voltage (POK).
The AS1330 is available in a TDFN (2x2mm) 8-pin package.
2 Key Features
Input Voltage Range: 0.6V to 3.0V
Adjustable Output Voltage Range: 1.8V to 3.3V
Fixed Output Voltage: 1.8V, 3.0V
0.85V Low Start-Up Voltage
4MHz Fixed-Frequency
91% Efficiency
Delivers 150mA @ 3.3V (from Single AA Cell)
Automatic Powersave Operation for light Loads
Output Disconnect during Shutdown
Anti-Ringing Control minimizes EMI
Power Okay and Sense pin
TDFN (2x2mm) 8-pin Package
3 Applications
The AS1330 is ideal for space critical applications where ultra-small
size is critical as in medical diagnostic equipment, hand-held
instruments, digital cameras, MP3 players, GPS receivers, and PC
or Memory cards.
