The ISL6722A and ISL6723A are low power, single-ended pulse width modulating (PWM) current mode controllers designed for a wide range of DC/DC conversion applications including boost, flyback, and isolated output configurations. They offer adjustable operating frequency, adjustable soft-start, and other features.
The ISL6722A is a low‑power, single‑ended PWM current‑mode controller designed for a wide range of DC/DC conversion applications such as boost, flyback, and isolated output configurations. It offers a low‑power sleep mode, adjustable switching frequency up to 1 MHz, and a 1 A MOSFET gate driver.
Key features include a 100 pA start‑up current, fast transient response, adjustable soft‑start and slope compensation, and ROHS‑compliant Pb‑free packaging. The device is supplied in 16‑lead QFN, SOIC, and TSSOP packages and operates from –40 °C to +105 °C with a maximum junction temperature of 150 °C.
