Note 1: All devices are 100% tested at +25°C. All limits over temperature are guaranteed by design, not production tested.
Note 2: Guaranteed by design, not production tested.
Note 3: Parameter measured at trip point of latch with VFB = 0V (MAX5070A/MAX5070B only).
Note 4: Gain is defined as A = ∆VCOMP/∆VCS, 0 ≤ VCS ≤ 0.8V.
Note 5: Output Frequency equals oscillator frequency for MAX5070A/MAX5071A. Output frequency is one-half oscillator frequency
for MAX5070B/MAX5071B/MAX5071C.
(VCC = 15V, TA = +25°C, unless otherwise noted.)
