APW7095/A
6-Channel DC/DC Converter Control IC
Features
General Description
• Supports for Synchronous Rectification
The APW7095/A is a 6-channel, frequency-settable, volt-
(CH1, CH2, and CH5)
age-mode, DC/DC control IC providing a complete power
supply solution for high-performance portable digital
• Supports for Down or Up-Down Zeta Conversions _{cameras. The APW7095/A uses pulse-width-modulation}
(CH1 and APW7095 CH2)
• Supports for Up, Flyback, or Up-Down SEPIC
Conversions (APW7095A CH2, CH3, APW7095
CH4, CH5, and CH6)
• Supports for Inverting Conversion
(APW7095A CH4)
• Low Start-up Voltage : 1.4V (CH6)
• Power Supply Voltage Range
- CH1 to CH5 : 3.0V to 6.5V
- CH6 : 2.4V to 6.5V
• 1% Reference Voltage Accuracy
(PWM) and synchronous rectification for high efficiency
step-up, step-down, up-down, and inverting converters
with free input and output settings in 2 or 4-cell AA, 1-cell
lithium-ion (Li+), and dual-battery designs. The APW7095/
A incorporates error amplifiers, output short-circuit
detection, under-voltage lockout, soft-start, and output
switch control into a chip. The AP7095/A improves
performance, component count, and size compared to
conventional multi-channel controllers.
The APW7095/A has a power-good indicator (PGOOD)
that signals when CH1 output is within ±10% of the set
voltage by monitoring IN1 pin.
The APW7095/A is available in compact 48-pin plastic
LQFP and TQFN packages.
• Wide Operating Frequency 100kHz to 1MHz
• Soft-Start Function (CH1 to 6)
Applications
• Power Good (PGOOD) Indicator for CH1
• Low Shutdown Current
• Output Short-Circuit Detections
• Lead Free and Green Devices Available
• Digital Camera
• Camcorder
• Hand-Held Instrument
(RoHS Compliant)
