Design Guide
Introduction
The PeakSwitch family is a highly integrated, monolithic,
off-line switcher IC designed for use in power supplies that have
to deliver peak loads for short durations. Example applications
include inkjet printers, audio amplifiers and DVRs. When peak
power is required, the effective switching frequency can approach
277 kHz, allowing a transformer with a small core size to be used.
Innovative proprietary features, such as adaptive switching cycle
on-time control, adaptive current limit, AC line sense and fast
AC reset greatly simplify the design. This reduces engineering
design time and system cost while providing complete
system-level protection and robust functionality.
Each member of the family has a high-voltage power MOSFET
and its controller integrated onto the same die. Internal start-
up bias current is drawn from a high-voltage current source
connected to the DRAIN pin, eliminating the need for external
start-up components. The internal oscillator is frequency

modulated (jitter) to reduce EMI. In addition, the ICs have
integrated functions that provide system-level protection. The
auto-restart function limits the dissipation in the MOSFET, the
transformer and the output diode during overload, output short-
circuit and open-loop conditions, while the auto-recovering
hysteretic thermal shutdown function disables MOSFET
switching during a thermal fault. On-time extension enables
more power to be delivered at low line and extends hold-up
time. The smart AC line sense and undervoltage lockout
(UVLO) functions enable the IC to latch off whenever a fault
activates the auto-restart function, and to be reset quickly after
AC power is removed.
Power Integrations’ EcoSmart
designed around the PeakSwitch family members to consume
<300 mW of no-load power and to meet harmonized energy
efficiency standards such as the California Energy Commission
(CEC), EU and ENERGY STAR.
