ON Semiconductor FSL106HR
FSL106HR
Green Mode Power Switch
Description
The FSL106HR integrated Pulse Width Modulator (PWM) and
SENSEFET® is specifically designed for highperformance offline
SwitchMode Power Supplies (SMPS) with minimal external
components. FSL106HR includes integrated highvoltage power
switching regulators that combine an avalancherugged SENSEFET
with a currentmode PWM control block.
The integrated PWM controller includes: UnderVoltage Lockout
(UVLO) protection, LeadingEdge Blanking (LEB), a frequency
generator for EMI attenuation, an optimized gate turnon/turnoff
driver, Thermal Shutdown (TSD) protection, and
temperaturecompensated precision current sources for loop
compensation and fault protection circuitry. The FSL106HR offers
good softstart performance. When compared to a discrete MOSFET
and controller or RCC switching converter solution, the FSL106HR
reduces total component count, design size, and weight; while
increasing efficiency, productivity, and system reliability. This device
provides a basic platform that is well suited for the design of
costeffective flyback converters.

PIN DEFINITIONS
Pin No. Name
Description
1 GND Ground. SENSEFET source terminal on the primary side and internal control ground.
Positive Supply Voltage Input. Although connected to an auxiliary transformer winding, current is supplied from pin
2 VCC 5 (VSTR) via an internal switch during startup (see Figure 2). Once VCC reaches the UVLO upper threshold (12 V),
the internal startup switch opens and device power is supplied via the auxiliary transformer winding.
Feedback Voltage. The noninverting input to the PWM comparator, it has a 0.4 mA current source connected inter-
3 VFB nally, while a capacitor and optocoupler are typically connected externally. There is a delay while charging external
capacitor CFB from 2.4 V to 6 V using an internal 5 mA current source. This delay prevents false triggering under tran-
sient conditions, but still allows the protection mechanism to operate under true overload conditions.
Peak Current Limit. Adjusts the peak current limit of the SENSEFET. The feedback 0.4 mA current source is divert-
4 IPK ed to the parallel combination of an internal 6 kW resistor and any external resistor to GND on this pin to determine
the peak current limit.

VSTR
Drain
Startup. Connected to the rectified AC line voltage source. At startup, the internal switch supplies internal bias and
charges an external storage capacitor placed between the VCC pin and ground. Once VCC reaches 12 V, the internal
switch is opened.
Drain. Designed to connect directly to the primary lead of the transformer and capable of switching a maximum of
650 V. Minimizing the length of the trace connecting these pins to the transformer decreases leakage inductance.
