Dual PWM Controller with SCP/DTC Function
General Description
The FP5462 is a single chip composed of a 2.5V precision voltage reference regulator,
totem-pole output stages, two pulse width modulation control circuits each with one error amplifier and
one duty comparator (DTC). Its built-in functions includes under-voltage lockout circuit (UVLO) and
short circuit protection circuit (SCP). With above features, it offers space and low cost solutions in
many applications such as the DC / DC converter.
FP5462, a high performance IC, is designed to complete a control circuit with few external
components. The circuit diagram of the typical application example is shown in below.
Features
Wide Operating Voltage Range: 3.6~40V
Fixed Reference Voltage: 2.5V
Reference Voltage Precision: 1%
Oscillator Frequency: Max. 500KHz
Low Quiescent Supply Current Under 3.5mA
Totem-pole Output Stage
Variable Duty Control (DTC)
UVLO Protection Function
SCP Protection Function (Threshold Voltage: 1.3V)
Package: SOP-16L / SSOP-16L
Applications
DC / DC Converters for Video Cameras and TFT LCD Monitor Etc.
1-ch Boost/1-ch Buck Topology Converter
