GENERAL DESCRIPTION
The LSP3601 is a boost topology switching regulator
control IC for battery-used applications field. The
LSP3601 includes a totem-pole single output stage
for driving NPN transistor or N-MOS, high precision
reference (0.5V) for comparing output voltage with
feedback amplifier, an internal dead-time control for
controlling the minimum duty cycle, programmable
soft start with short circuit protection function and
logic level control for operating mode or standby
mode.
FEATURES
Wide supply voltage operating range: 1.8 to 15V
Reference voltage precision: 4%
Low current consumption:
Operation Mode 5.5mA
Standby Mode: 1A
High speed oscillator frequency: 1MHz max
Programmable Soft Start function (SS)
Short Circuit Protection function (SCP)
Totem-pole output with adjustable on/off current
(for NPN transistors or n-channel MOSFET)
Logic level control stand-by mode function
Package: SOP8/MSOP8/TSSOP8
