The LM5021 features include an ultra- • Synchronizable Oscillator low (25 µA) start-up current, which minimizes power • Adjustable Soft-Start losses in the high voltage start-up network. A skip • Integrated 0.7-A Peak Gate Driver cycle mode reduces power consumption with light loads for energy conserving applications (ENERGY • Direct Opto-Coupler Interface STAR®, CECP, and so forth). Additional features • Maximum Duty Cycle Limiting (80% for LM5021-1 include under-voltage lockout, cycle-by-cycle current or 50% for LM5021-2) limit, hiccup mode overload protection, slope • Slope Compensation (LM5021-1 Only) compensation, soft-start and oscillator synchronization capability. This high performance 8- • Undervoltage Lockout (UVLO) with Hysteresis pin IC has total propagation delays less than 100 ns • Cycle-by-Cycle Overcurrent Protection and a 1-MHz capable oscillator that is programmed • Hiccup Mode for Continuous Overload Protection with a single resistor. • Leading Edge Blanking of Current Sense Signal Device Information(1) • Package: VSSOP-8 PART NUMBER PACKAGE BODY SIZE (NOM) LM5021-Q1 VSSOP (8) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
