STEP-UP OR DOWN, SINGLE-COIL, PWM CONTROL
SWITCHING REGULATOR CONTROLLER
S-8460
Seiko Instruments Inc.
1
The S-8460 is a PWM control CMOS step-up and step-down
switching regulator controller which consists of an automatic-selection
control circuit for step-up and step-down, a reference voltage circuit,
an oscillation circuit, an error amplifier, a phase compensation circuit,
etc.
The automatic-selection control circuit for step-up and step-
down in PWM control realizes a high performance step-up and step-
down switching regulator operating on one coil. With an external N-
channel power MOS, the S-8460 is ideal for applications requiring
high efficiency and a high current output.
The S-8460 realizes low ripple, high efficiency and excellent
characteristics by featuring a PWM switching controller that can
change the duty ratio linearly from 0%, and the optimized error
amplifier and phase compensation circuit.
Features
Single-coil, step-up or step-down switching realizes high efficiency.
High efficiency is realized by using only N-channel power MOS FET as an external power MOS
Synchronous rectification at step-down operation
Input voltage :
2.2 to 18.0 V
